Logical Conservative quite the contrary - America was settled not so much for economic return but for getting out from under what they considered oppressive government.

@@isaacarthurSFIAWell, Isaac, the problem is that everybody understands the term "Kickstarting", and "launching" might not pop off the screen in the same way for new potential viewers, who might skip over your video.
Launching is indeed a great play on words, but I still think kickstarting gets across the premise of what we were trying to answer here more clearly. Space X, Blue Origin, XCOR, etc. have literally already launched industry into space, but the question is more: what is the payload and the framework that will sustain it ongoing? Great video, Isaac, just what I was hoping for!
It's really easy to manufacture high precision ball bearings in microgravity. You just spray the liquid metal with the desired drop size, and wait for it to cool down. Cold welding can be a problem but you can also do it on purpose. Telescopes obviously are better, and so are huge structures, like a scaled up version of LIGO, or LHC. The problem is it has to become self sufficient pretty quickly, because launch costs are enormous. Sending up smaller machines to collect materials and slowly build large versions could be interesting.
While I always enjoy seeing videos about what could be done in the eventual future with colonisation and interstellar travel, ones like this about the now future are by far the most exciting to me. Thanks for all of it Issac; love your work. :)
Isaac, please never stop making your excellent and inspirational content, right up until there's no more internet and electricity with which to record and distribute it. I'm feeling introspective tonight on behalf of humanity. What a time to be alive. I think about this often. If I could pick any time to be alive, it would probably be now. I, as a woman with a daughter, live in the time wherein my access to education and equal protection under the law is the greatest in history. Rates of violence and needless suffering are the lowest they ever have been and are on a long term decline. Civilization has tended, when viewed on the whole, though imperfectly and hesitantly and with occasional interruptions of tragedy, to foster the development of justice, empathy, and knowledge. But conversely, this progress has cost millions of years' worth of non-renewable energy, the exploitation of which, in a geological instant, has set the world on a trajectory which will destroy habitat, human or otherwise, in the next few short centuries and trigger a sixth mass extinction which is already underway. The very Scientific Method which has liberated humanity, or at least those members of humanity willing to be liberated, from superstition and resulted in our species' collective knowledge about reality, which i consider one of the most meaningful pursuits possible, has also resulted in humanity living under the guillotine of at least one Doomsday technology with more on the way, not to mention a technologically advanced and ruthlessly efficient food production system which nonetheless operates on a knife's edge and is woefully vulnerable to the very climactic changes now underway. A staggering portion of the privileged population of this world is selfish, myopic, and arrogantly ignorant, despite living in plenty and having instantaneous access to the collective knowledge of the species. That same privileged population, of which i am a member, lives in plenty on the backs of a vast global underclass living in squalor, but whose uplift to our standard of living would only quicken the demise of the already tottering global ecosystem. We are witnessing the peak of civilization, perhaps of intelligent evolution in this galaxy and/or of this phase of the universe. It is a privilege and a torture, because one can see the potential for much greater things never to be achieved, because we didn't live up to what we could have been. We sit at the crest of an evolutionary wave that has spent the last 250 million years grinding entire ecosystems into dust, our ancestors barely managing to stay alive in enough numbers to avoid extinction and give birth to this species, which itself magnified the suffering of its members through the unique combination of vulnerability and cruelty whose potential only sentience confers. Perhaps if more members of our species posessed the knowledge and perspective to understand this saga of history and realize how many more lives could transpire if we didn't unnecessarily cut that saga short, things could have been different. As it is, I won't say we have entirety squandered that legacy. We have accomplished much. Learned much. But we could have been so much more. You, Isaac, have helped me envision the potential of humanity, and that alone is worth enduring the struggle for survival, even in the absence of all the other great benefits of being alive and in possession of a sentient consciousness. Thank you.
I don't deny it's possible that we could overcome these obstacles, but it's looking less and less likely. I think it's going to be too little too late. We're not talking about mere millions of climate refugees fleeing coastal regions due to sea level rise. We're talking ecological collapse, which will affect everyone everywhere and kick off global conflict over resources. This has already begun and will increase exponentially along with climate change. There's another RUclipsr i like to quote periodically: "we are so fucked."
TOPIC SUGGESTION: Wealth. What is wealth? Many think of it as pieces of paper or numbers in a bank account, but ancients used cows, salt or giant stones as well as precious metals as wealth. Post apocalyptic stories often show oil or metal as wealth. However, shows like Star Trek, arguably our first post-scarcity popular sci-fi show, seems fairly clueless about how to represent wealth. My suggestion for an episode would be to speculate what forms wealth would take starting at the kickstarter stage up into the post-scarcity stage with perhaps a detour into some of the darker possibilities, such as post-apocalyptic economies.
You will get better discussions on Isaac's reddit page. www.reddit.com/r/IsaacArthur/ Wealth is related to scarcity. Value will take several forms including information, mass, momentum, accessible energy content, neutron content, and location.
I would wager litteral power (electrical or some other medium), Some decendant of Bitcoin that finally gets stable enough to be a useful currency, or something more abstract like creative works of art and such. All or a combination of seems reasonable, with the latter being considerably more viable if we figure out Biological or digital immortality
There was a Next Generation episode that touched on the topic of what wealth would be in the future. The crew collected some frozen people from the 20th (or 21st?) century, one of whom was a wealthy industrialist sure that his holding would have multiplied since the group were to have been thawed when their illnesses were curable. He was sure Picard was a man of only moderate means since he was restricted to military power. Our thawed industrialists learned 1) his appointed heirs spent it all with the help of his appointed legal team. 2 with the absence of physical scarcity of any kind, wealth was now measured in creativity, social power and military effectiveness as related to species survival in a galaxy that didn't care if we survived. So, artistic dominance, social influence or political/military control, all "wealth" was measured by your ability to influence the action of others. The industrialist understood the Romulans, to both the advantage and disadvantage of Picard. He and the other thawed people were then shipped to earth, where we viewers felt they would soon catch on to the new world of no poverty, but many roads to wealth/control, all optional, and apparently chosen by only a few. In 1900, rich people had indoor plumbing, reliable central heat and food even in the middle of winter. In 1950, people of average means had all the above. In 2018 USA, most people in the bottom 10% income have access to all of the above---and to color TV, and internet in public libraries. The path is uneven, but it appears we are apt to end up in Picard's Next Generation future where all of the material things wealth once made available to the upper 10%, even the upper 1%, will be so available to all, static things, even bank balances, will have no value. Wealth will be determined by current activity and current accomplishment.
@@friendlyone2706 I saw that episode when it first came out (I think it's called The Neutral Zone) and I was dissatisfied with how dismissive they were of wealth and the very concept of economics. (I was also disappointed that we didn't follow up with the revived corpsicles. By the way, what is a "low mileage pit woofie"?) Your analysis of how the poorest among us is wealthier than an ancient king, depending on how you measure wealth, is quite correct and is at the heart of the wealth question. Even if gold and diamonds become as worthless as sand, I suspect we will still need some method of tracking how much someone has contributed to society. (And I understand that money as we understand it can be taken through force or fraud, but when things work it is a good medium of exchange that is more convenient than barter.)
As always amazing video! But a few considerations I think should be added. First, diamonds aren't rare on earth. They are stupidly common. Their value is a result of artificial restriction by the DeBeers mining group that holds nearly a monopoly on diamond mining. As well, they have lobbied to make it such that diamonds grown in a lab (which are cheaper and more consistently better quality) can't legally be called "gem stones" and so can't be sold for the same value as mined diamonds. Second, on the topic of rarity, I think an important distinction should be made for the two types of rare metals (generally). There's gold and silver, which although have their uses are mostly valuable simply based on rarity but otherwise we don't really need that much of. And then there are ones like platinum which are also expensive due to rarity, but if we suddenly had a lot of it we would also have sooooooo many technologies that could benefit off of cheaper access to platinum. The reason we don't see it used more is BECAUSE it's so rare, and so if it's rarity decreased, in theory, demand should increase unlike gold and silver. This is sort of getting sidetracked to the post scarcity problem often discussed on this channel, but switching to a currency/resource valuation approach based on usefulness may be an interesting solution to explore, as it decouples value from rarity.
Arthursdays are the only reason for the rest of the week existing. Something to lead up to Arthursday. You sir, are my hero. Cheers and be well friend.
Platinum group metals don't occur naturally in earth's crust. As such they would not be found in abundance kilometers down. All deposits are relatively shallow and very rare. It's said that all the platinum (aside from it's group metals) refined to date could fit in one person's living room. The stuff is extremely rare. Orders of magnitude more rare on earth than silver or gold. And for certain applications it's also far more useful industrially. Gold and silver refinement would be almost just a near meaningless bi-product of high abundance platinum group metal mining. It would be that as a resource which would be a principle driver if anything. There wouldn't be much depreciation in value either. Tech's thirst for such metals is insatiable. The more one manages to come up with the more will be needed. The catalytic properties alone are more than worth it. Identify an assured high purity and high abundance source of the stuff and a space industry explosion will soon follow.
Space industry is one of those things I think governments should be working together to invest in. Not cause they're super-profitable now, but the benefits to humanity (and whatever might come after us XD)
@@HxH2011DRA Also, I think there should be a ''Space-Industrial Complex'' and an International Space Exploration Bank to finance (materially) poorer countries' space programs.

A great terrestrial parable for mining is aluminum. It was once more expensive than gold, because it was so difficult to mine... now, we wrap our food in it and throw it away.
Asteroids have been hitting the moon for a long time, and turning into moon dust. Moon dust can be easily separated by mass , magnetism, etc. These powdered metals make ideal feed stock for 3D printers. The vacuum is very handy. If a target form is heated with a big mirror and metal dust is fired at that target at high speed, and that dust is controlled by a magnetic field, you can print large metal items in much the same way that old Cathode Ray Tubes worked.
I would like to see an updated version of this, focusing on near-term LEO and moon manufacturing. Next 5 years, 10 years, 20 years, etc. ISS experiments, Varda's pharma experiments in LEO, etc. A lot has changed in the last five years in space flight and technology since this was published.

What if we can plan a whole industry, backtraced from the things we used to get there? You can land with BFR's on the Moon or Mars and get out of there. So what about carrying whatever you need to make BFR's to the moon like: 1. Carry the CNC machines that make the special parts. 2. Carry the machines that are used to make the CNC machines that make the special parts. 3. Carry the machines that are needed in Earth to extract and refine the raw materials All in all, if someone can engineer the whole self sustainable system where not even a single bolt or microchip or anything is needed to be brought from elsewhere, we are gonna be in a good way. Offcourse, that is a great investment to do without knowing before hand what kind of raw materials are available there. So my guess is that robotic miners should be sent to moon first and start excavating and gathering raw materials while only the infrastructure for making more mining equipment is used at first. If they are all robotic and quite automated not a lot of personnel is needed on site. If the site expands, it will be possible already to build some farming facilities to feed the people there. All in all, whatever we saw in Mars documentary, lets apply it to the safety of our own moon first. And lest please do this before 2050.
Great video! I've been thinking about this subject a lot lately, and I also feel we're getting close to having a considerable space industry. I've also been thinking a lot about it in terms of investment opportunities, both to make money for myself and to support something I'm passionate about. But to a non-genius like myself distinguishing between legitimate companies, with products that are realistic and useful, and scams is quite hard. So I really appreciate people like you who make these subjects easy enough for us regular folk to understand. Cheers!
Combining early space industries with life extension therapies, I could see the low gravity environment used to combat the bone and joint damage accumulated through decades of abrasion. While we may develop medicine to combat it, it's not going to be that effective if these joints are still in use, actively wearing down the regenerating tissue. Less stress in low gravity will make that more successful and might even work without the aid of medicine. As soon as we have some space tourism established, I can see clinics pop up to treat this and other diseases in space instead.
I can see mining asteroids for raw materials but not shipping the raw/processed ore to Earth. Rather shipping the material to Moon-based factories/refineries that then ship needed/wanted products to earth.
It might be possible to use a skyhook to reduce the costs of space travel allowing for powerstalites and asteroid mining, with the mass from the asteroid being split between raw materials for more power satellites and precious metals being sent back to earth it would be one of the largest undertakings in history but the combination of the two and the fact that one needs more matter to be lifted and the other needs more matter to be lowered means that they could balance each other for use on a medium to large skyhook.
I can't help but imagine what sports will take place in Zero gravity. We often think no sport will usurp football (soccer) as the global sport of choice and that might be accurate but the next sport doesn't necessarily have to be global. Though that might be something that doesn't come about until after people are in space for a while as sports ball tends to start as a leisure time activity before becoming something more.
New knowledge will be the coin of future wealth. The "dark" side of the moon, blocking all earth noise contamination, will be a perfect source of many varieties of observatories to mine new knowledge.
Thank you for another fascinating video! Smart investors should start buying stock in Planetary Resources and other future space mining companies to cash in early on the coming space industry boom.

3:04 '..and suddenly we need to build some massive whale 🐳 guns to launch whales 🐋 into space, and with THE MAID 🤰🏽 we can now use them for launching ''other things'' That's TOO MUCH coffee, Isaac!
You forgot the most important application that could be done right now: massive shades in Lagrangian L1 reducing the solar influx by 3-4%, enough to cancel any kind of "global warming" effect or fluctuation in the Sun's radiation (the main trigger in what we call "global warming" and ice ages). At the same time, when and if a Maunder Minimum will take place, the solar shades / mirrors could reflect back more energy, heating the Earth or part of it. Also, Philip Lubin could use those mirrors to generate some energy and power his giant 10 GW array of 1928 nm lasers in order to deflect any asteroid heading to earth. Or use it as a giant space weapon against totalitarians. The cost for all of this is just a fraction of what we spend now on "CO2 reduction" and "green certificates". All the industries would benefit from a lower cost of energy, if that is produced from coal with sequestration and in remote places, and at the same time, the energy bill would not include any kind of wind&solar subsidies (that will go to this massive laser space project). Win / Win for all and a massive incentive for a Moon Base, where all of that manufacturing for the 1500 km mesh array will take place. ruclips.net/video/XwYJZqBB0ms/видео.html 1.bp.blogspot.com/_JtKzQh0R9Tg/ShoeWDFE8PI/AAAAAAAAAoI/8NiaXweN9dY/s1600/how-to-move-the-sun3.jpg

@@isaacarthurSFIAWell, Isaac, the problem is that everybody understands the term "Kickstarting", and "launching" might not pop off the screen in the same way for new potential viewers, who might skip over your video.
@@isaacarthurSFIA never trust polls; just ask Hillary :D
Launching is indeed a great play on words, but I still think kickstarting gets across the premise of what we were trying to answer here more clearly. Space X, Blue Origin, XCOR, etc. have literally already launched industry into space, but the question is more: what is the payload and the framework that will sustain it ongoing? Great video, Isaac, just what I was hoping for!
It's really easy to manufacture high precision ball bearings in microgravity. You just spray the liquid metal with the desired drop size, and wait for it to cool down. Cold welding can be a problem but you can also do it on purpose. Telescopes obviously are better, and so are huge structures, like a scaled up version of LIGO, or LHC.
The problem is it has to become self sufficient pretty quickly, because launch costs are enormous. Sending up smaller machines to collect materials and slowly build large versions could be interesting.
Love your videos ..... I literally watch them listen to them daily. While working .... And when just hanging out with my kids. (I have a ton of kids)
Depending on how old the kids are it might be good for them to hear it too
Im one of them.. thanks grownups
. I could not do it all with easy grace without you 🤣
That’s seriously impressive, I only have 80-85 lbs of kiddos.. but they are finicky eaters.
average child weight between 2/16 is 34,92 thats 28,63 chindren to the ton. i realy though it would be more
@@PatandSylus RU Sirius, they'd put their Iphones down to listen? Would that it were true!

While I always enjoy seeing videos about what could be done in the eventual future with colonisation and interstellar travel, ones like this about the now future are by far the most exciting to me.
Thanks for all of it Issac; love your work. :)
Isaac, please never stop making your excellent and inspirational content, right up until there's no more internet and electricity with which to record and distribute it. I'm feeling introspective tonight on behalf of humanity. What a time to be alive. I think about this often. If I could pick any time to be alive, it would probably be now. I, as a woman with a daughter, live in the time wherein my access to education and equal protection under the law is the greatest in history. Rates of violence and needless suffering are the lowest they ever have been and are on a long term decline. Civilization has tended, when viewed on the whole, though imperfectly and hesitantly and with occasional interruptions of tragedy, to foster the development of justice, empathy, and knowledge. But conversely, this progress has cost millions of years' worth of non-renewable energy, the exploitation of which, in a geological instant, has set the world on a trajectory which will destroy habitat, human or otherwise, in the next few short centuries and trigger a sixth mass extinction which is already underway. The very Scientific Method which has liberated humanity, or at least those members of humanity willing to be liberated, from superstition and resulted in our species' collective knowledge about reality, which i consider one of the most meaningful pursuits possible, has also resulted in humanity living under the guillotine of at least one Doomsday technology with more on the way, not to mention a technologically advanced and ruthlessly efficient food production system which nonetheless operates on a knife's edge and is woefully vulnerable to the very climactic changes now underway. A staggering portion of the privileged population of this world is selfish, myopic, and arrogantly ignorant, despite living in plenty and having instantaneous access to the collective knowledge of the species. That same privileged population, of which i am a member, lives in plenty on the backs of a vast global underclass living in squalor, but whose uplift to our standard of living would only quicken the demise of the already tottering global ecosystem.
We are witnessing the peak of civilization, perhaps of intelligent evolution in this galaxy and/or of this phase of the universe. It is a privilege and a torture, because one can see the potential for much greater things never to be achieved, because we didn't live up to what we could have been. We sit at the crest of an evolutionary wave that has spent the last 250 million years grinding entire ecosystems into dust, our ancestors barely managing to stay alive in enough numbers to avoid extinction and give birth to this species, which itself magnified the suffering of its members through the unique combination of vulnerability and cruelty whose potential only sentience confers. Perhaps if more members of our species posessed the knowledge and perspective to understand this saga of history and realize how many more lives could transpire if we didn't unnecessarily cut that saga short, things could have been different. As it is, I won't say we have entirety squandered that legacy. We have accomplished much. Learned much. But we could have been so much more.
You, Isaac, have helped me envision the potential of humanity, and that alone is worth enduring the struggle for survival, even in the absence of all the other great benefits of being alive and in possession of a sentient consciousness. Thank you.
I don't deny it's possible that we could overcome these obstacles, but it's looking less and less likely. I think it's going to be too little too late. We're not talking about mere millions of climate refugees fleeing coastal regions due to sea level rise. We're talking ecological collapse, which will affect everyone everywhere and kick off global conflict over resources. This has already begun and will increase exponentially along with climate change.
There's another RUclipsr i like to quote periodically: "we are so fucked."
TOPIC SUGGESTION: Wealth.
What is wealth? Many think of it as pieces of paper or numbers in a bank account, but ancients used cows, salt or giant stones as well as precious metals as wealth. Post apocalyptic stories often show oil or metal as wealth. However, shows like Star Trek, arguably our first post-scarcity popular sci-fi show, seems fairly clueless about how to represent wealth.
My suggestion for an episode would be to speculate what forms wealth would take starting at the kickstarter stage up into the post-scarcity stage with perhaps a detour into some of the darker possibilities, such as post-apocalyptic economies.
awesome idea, i really want to watch this!
You will get better discussions on Isaac's reddit page. www.reddit.com/r/IsaacArthur/
Wealth is related to scarcity. Value will take several forms including information, mass, momentum, accessible energy content, neutron content, and location.
I would wager litteral power (electrical or some other medium), Some decendant of Bitcoin that finally gets stable enough to be a useful currency, or something more abstract like creative works of art and such.
All or a combination of seems reasonable, with the latter being considerably more viable if we figure out Biological or digital immortality
There was a Next Generation episode that touched on the topic of what wealth would be in the future.
The crew collected some frozen people from the 20th (or 21st?) century, one of whom was a wealthy industrialist sure that his holding would have multiplied since the group were to have been thawed when their illnesses were curable. He was sure Picard was a man of only moderate means since he was restricted to military power. Our thawed industrialists learned 1) his appointed heirs spent it all with the help of his appointed legal team.
2 with the absence of physical scarcity of any kind, wealth was now measured in creativity, social power and military effectiveness as related to species survival in a galaxy that didn't care if we survived.
So, artistic dominance, social influence or political/military control, all "wealth" was measured by your ability to influence the action of others.
The industrialist understood the Romulans, to both the advantage and disadvantage of Picard.
He and the other thawed people were then shipped to earth, where we viewers felt they would soon catch on to the new world of no poverty, but many roads to wealth/control, all optional, and apparently chosen by only a few.
In 1900, rich people had indoor plumbing, reliable central heat and food even in the middle of winter.
In 1950, people of average means had all the above.
In 2018 USA, most people in the bottom 10% income have access to all of the above---and to color TV, and internet in public libraries.
The path is uneven, but it appears we are apt to end up in Picard's Next Generation future where all of the material things wealth once made available to the upper 10%, even the upper 1%, will be so available to all, static things, even bank balances, will have no value. Wealth will be determined by current activity and current accomplishment.
@@friendlyone2706 I saw that episode when it first came out (I think it's called The Neutral Zone) and I was dissatisfied with how dismissive they were of wealth and the very concept of economics. (I was also disappointed that we didn't follow up with the revived corpsicles. By the way, what is a "low mileage pit woofie"?)
Your analysis of how the poorest among us is wealthier than an ancient king, depending on how you measure wealth, is quite correct and is at the heart of the wealth question. Even if gold and diamonds become as worthless as sand, I suspect we will still need some method of tracking how much someone has contributed to society. (And I understand that money as we understand it can be taken through force or fraud, but when things work it is a good medium of exchange that is more convenient than barter.)
Thanks Isaac and Merry Christmas! More excellence
As always amazing video! But a few considerations I think should be added. First, diamonds aren't rare on earth. They are stupidly common. Their value is a result of artificial restriction by the DeBeers mining group that holds nearly a monopoly on diamond mining. As well, they have lobbied to make it such that diamonds grown in a lab (which are cheaper and more consistently better quality) can't legally be called "gem stones" and so can't be sold for the same value as mined diamonds. Second, on the topic of rarity, I think an important distinction should be made for the two types of rare metals (generally). There's gold and silver, which although have their uses are mostly valuable simply based on rarity but otherwise we don't really need that much of. And then there are ones like platinum which are also expensive due to rarity, but if we suddenly had a lot of it we would also have sooooooo many technologies that could benefit off of cheaper access to platinum. The reason we don't see it used more is BECAUSE it's so rare, and so if it's rarity decreased, in theory, demand should increase unlike gold and silver. This is sort of getting sidetracked to the post scarcity problem often discussed on this channel, but switching to a currency/resource valuation approach based on usefulness may be an interesting solution to explore, as it decouples value from rarity.
Drinks and munchies for me and the kiddo, Check!. Happy Arthursday everyone!
Willing and ready to be a space farmer!
Arthursdays are the only reason for the rest of the week existing. Something to lead up to Arthursday. You sir, are my hero. Cheers and be well friend.
Platinum group metals don't occur naturally in earth's crust. As such they would not be found in abundance kilometers down. All deposits are relatively shallow and very rare. It's said that all the platinum (aside from it's group metals) refined to date could fit in one person's living room. The stuff is extremely rare. Orders of magnitude more rare on earth than silver or gold. And for certain applications it's also far more useful industrially. Gold and silver refinement would be almost just a near meaningless bi-product of high abundance platinum group metal mining. It would be that as a resource which would be a principle driver if anything.
There wouldn't be much depreciation in value either. Tech's thirst for such metals is insatiable. The more one manages to come up with the more will be needed. The catalytic properties alone are more than worth it. Identify an assured high purity and high abundance source of the stuff and a space industry explosion will soon follow.
Agreed. I'm looking primarily for platinums.
Underpants gnomes!!! One of my favorite reference at the workplace to highlight gaps in anybody's plans :D
Sorry for the early release.... and this awesome video which made my day?!
Space industry is one of those things I think governments should be working together to invest in. Not cause they're super-profitable now, but the benefits to humanity (and whatever might come after us XD)
Exactly, that's why I want every country to have a Space Industry, a Space Agency, Space Technology companies and a Space Program.

Thank you so much, I am not doing well in school and we barely have like half an hour of Astronomy per week, its hard for me to keep going in school since I hate most of the subjects, but I absolutely love Astronomy, SF and Architecture your channel serves the love I need xD. Maybe you might even make me change my mind about my future job, you are truly inspiring and you made me think about so much, Thank you.
This channel is incredibly good. This is _the_ hardest scifi there is.
It's hardly scifi. Almost scinonfi.
Awesome! Thanks Isaac! You answered quite a few questions I had about the initial push into the cosmos. Can't wait to get out there!

Yes, like Alan Shepard golfing on the moon!!
This channel ROCKS! I enjoy every single one of your videos. Keep up the great work!!
Thank you Isaac, very cool.
A great terrestrial parable for mining is aluminum. It was once more expensive than gold, because it was so difficult to mine... now, we wrap our food in it and throw it away.
The beginning and closing them is my favorite.

Asteroids have been hitting the moon for a long time, and turning into moon dust. Moon dust can be easily separated by mass , magnetism, etc. These powdered metals make ideal feed stock for 3D printers. The vacuum is very handy. If a target form is heated with a big mirror and metal dust is fired at that target at high speed, and that dust is controlled by a magnetic field, you can print large metal items in much the same way that old Cathode Ray Tubes worked.
Grounded, yet optimistic and inspirational as usual Isaac!

What if we can plan a whole industry, backtraced from the things we used to get there?
You can land with BFR's on the Moon or Mars and get out of there. So what about carrying whatever you need to make BFR's to the moon like:
1. Carry the CNC machines that make the special parts.
2. Carry the machines that are used to make the CNC machines that make the special parts.
3. Carry the machines that are needed in Earth to extract and refine the raw materials
All in all, if someone can engineer the whole self sustainable system where not even a single bolt or microchip or anything is needed to be brought from elsewhere, we are gonna be in a good way.
Offcourse, that is a great investment to do without knowing before hand what kind of raw materials are available there. So my guess is that robotic miners should be sent to moon first and start excavating and gathering raw materials while only the infrastructure for making more mining equipment is used at first. If they are all robotic and quite automated not a lot of personnel is needed on site. If the site expands, it will be possible already to build some farming facilities to feed the people there.
All in all, whatever we saw in Mars documentary, lets apply it to the safety of our own moon first. And lest please do this before 2050.
Great video thanks for sharing 👍
Aah, now I understand what the santa claus machine is about. Great episode as usual.
The people running backwards from 16:51 to 17:00 cracked me up.
you should see the famous episode "Backwards" from the "Red Dwarf" sci fi series on BBC years ago. You'd die laughing!!
thanks for this one isaac!
Great video! I've been thinking about this subject a lot lately, and I also feel we're getting close to having a considerable space industry. I've also been thinking a lot about it in terms of investment opportunities, both to make money for myself and to support something I'm passionate about. But to a non-genius like myself distinguishing between legitimate companies, with products that are realistic and useful, and scams is quite hard. So I really appreciate people like you who make these subjects easy enough for us regular folk to understand. Cheers!
Combining early space industries with life extension therapies, I could see the low gravity environment used to combat the bone and joint damage accumulated through decades of abrasion. While we may develop medicine to combat it, it's not going to be that effective if these joints are still in use, actively wearing down the regenerating tissue. Less stress in low gravity will make that more successful and might even work without the aid of medicine.
As soon as we have some space tourism established, I can see clinics pop up to treat this and other diseases in space instead.
Very cool!
I'm really excited for the Colonizing the Arctic Episode. It's something I've put a great deal of thought and research into.
I guess the project to deflect an incoming asteroid will kickstart the "Space Age"

I can see mining asteroids for raw materials but not shipping the raw/processed ore to Earth. Rather shipping the material to Moon-based factories/refineries that then ship needed/wanted products to earth.
that's in several of his other masterpieces!
One of the best episodes so far. Real "meat and potatoes" type of ideas here. More videos like this please.
It might be possible to use a skyhook to reduce the costs of space travel allowing for powerstalites and asteroid mining, with the mass from the asteroid being split between raw materials for more power satellites and precious metals being sent back to earth it would be one of the largest undertakings in history but the combination of the two and the fact that one needs more matter to be lifted and the other needs more matter to be lowered means that they could balance each other for use on a medium to large skyhook.
Mr. Arthur, this makes me wonder about space debris. How long until something drastic needs to be done? Possible modes of cleanup?
sounds like a future business venture: salvage and recycle of space junk.
I can't help but imagine what sports will take place in Zero gravity. We often think no sport will usurp football (soccer) as the global sport of choice and that might be accurate but the next sport doesn't necessarily have to be global. Though that might be something that doesn't come about until after people are in space for a while as sports ball tends to start as a leisure time activity before becoming something more.
interesting to think about, I could see some kind of zero G laser tag or paintball being fun.

Great that you point out the material science potential of space development. It isn't what most people consider sexy, but there's a reason we tend to name epochs of human history things like the Stone, Bronze, ect. Age ;)
3:04 '..and suddenly we need to build some massive whale 🐳 guns to launch whales 🐋 into space, and with THE MAID 🤰🏽 we can now use them for launching ''other things''
That's TOO MUCH coffee, Isaac!
You forgot the most important application that could be done right now: massive shades in Lagrangian L1 reducing the solar influx by 3-4%, enough to cancel any kind of "global warming" effect or fluctuation in the Sun's radiation (the main trigger in what we call "global warming" and ice ages). At the same time, when and if a Maunder Minimum will take place, the solar shades / mirrors could reflect back more energy, heating the Earth or part of it.
Also, Philip Lubin could use those mirrors to generate some energy and power his giant 10 GW array of 1928 nm lasers in order to deflect any asteroid heading to earth. Or use it as a giant space weapon against totalitarians. The cost for all of this is just a fraction of what we spend now on "CO2 reduction" and "green certificates". All the industries would benefit from a lower cost of energy, if that is produced from coal with sequestration and in remote places, and at the same time, the energy bill would not include any kind of wind&solar subsidies (that will go to this massive laser space project). Win / Win for all and a massive incentive for a Moon Base, where all of that manufacturing for the 1500 km mesh array will take place.
