    Thank you for your amazing work Lex. You are one of the most inspiring people I have encountered. I love how you strive to embody the polymath and seek succes in so many different fields from music to martial arts and engineering - you prove to me that it is possible to excell professionally as well as artistically and physically.
    I notice how much care you take to apply the best methods of hosting a youtube channel, including titles, video descriptions, outlines, introductions, adds, not to mention the amazing guests you have on and your well formulated questions for them. I appreciate your effort! I also like that you have a channel for clips that inspire you, drawing from only the best video content on youtube in my opinion. The short clips about specific subjects from episodes in your podcast is also well recieved. You take the time to catch the essentials from each episode, making it easier for us viewers to absorb as much of the most important information as possible.
    I study medicine and want to become a psychiatrist - like you, before you read "Artificial Intelligence: A Modern Approach", but now I am considering changing my path, or at least to try to implement artificial intelligence more into my field. There is a lot of data especially in my country of Denmark where medical registries are available to researchers. I know nothing about programming, but I want to learn, and you inspire me to try even if it will take 10 years. God bless you.

    I vividly remember seeing IBM's Shoebox demo at the 1962 Seattle World's Fair as a teenager. It was really amazing and an inspiration to me. It recognized ten digits and several control words. As I recall, it then calculated an arithmetic result. We've come a long way but it was a significant achievement then.

  • @VoiceOverEngineer

    I t think Rohit hit on something that sets Alexa part from Google which is verbosity. Google responds with a explanation of your command, maybe to promote conversation, but Rohit realizes sometimes it's a human machine interaction so Alexa just says "ok" vs Google saying "turning off all lights".
    I'd like to hear about how Home AI's can interpret a compound command and perhaps leveraging a command that was not very effective and weighing the follow up command as "gospel".
    Alexa "its too bright", "I don't know that" "living room lights 35%" "ok"

    I'm 99.9% positive that I've gotten ads based on conversations I was just having. If you've never seen an add for a specific resteraunt, and have a conversation about that place with a friend, then pull your phone out to look something up and the first ad banner is for that resteraunt. I'm not buying it. Its happened too often. I tend to do most of my browsing anon as well so my data footprint is smaller than most.

    Not to sound like a 'conspiracy guy'... but Rohit cannot be entirely truthful with his claim that Alexa records nothing until the wake word activates the microphone. In the recording history, the wake word is included in the audio clips. How is this possible if the microphone was not continuously recording before the conclusion of the wake word? It could simply be that there is continuous recording, but then dumping of, the data after say 1 second, but Rohit did not say that. I think in this age of privacy and devices, he should even more transparent than what he mentioned. Btw this is the same with 'Okay Google', but I am not sure if google makes the same claim that it is not continuously recording.

    • @w00tbassman
      @w00tbassman 4 года назад +2

      Just to clarify and be fair, at 48:15 Rohit answers "Is Alexa Listening?" with "No, Alexa listens only for the wake word." What he failed to share is how then are the wake words included in the recorded history. Microphones cannot record back in time. I believe requires an explanation in order to gain our trust.

    Great work, Lex, however, maybe because I'm German I see things more critically. I work in the same field of research, but with all the enthusiasm about new possibilities it's easy to forget that this another step to make people more dependable on technology and losing agency and touch with the world (Alexa deciding for you that you might need a table at a restaurant after going to the cinema... people are so predictable...) And after all, keep in mind, this is all targeted at doing more business and pushing consumerism.

Of course, people are free to believe that Amazon and Google have our best interests in mind, but as we know, data is the currency of the infomation economy.

    Lex, great as always. I would have liked more in-depth questioning on the topic of humor. Considering the importance of flow and context in the conversation, timing, slippary boundary between humor and appropriate conversation etc., what are the mechanisms used to decide on when/how/what humor to inject in the conversation? Are the 'jokes' complete sentences that are copied from a 'joke database' and repeated literally, or is the core of the joke changed as needed in the conversation? Maybe an opportunity for a dedicated topic in a future conversation.

    Re: Is it okay for an Alexa to be listening all the time? If its listening for commercial purposes, you are basically opening to door to a super intelligence whose goal it is to separate you from your money, which it will have no problem doing because its a super intelligence and you are not. Is that going to be healthy for you?

      Researcher at Alexa here. Before joining, I thought the same, "why can't you just download Alexa in your computer and just using locally?" It turns out that there are some good reasons why you would want Alexa to operate in the cloud. Off the top of my head, I can think of two main ones: 1) Privacy: it is possible in ML models to infer whether a piece of data was used as part of training, of if it is generalization. If a malicious actor had access to the models, and was dedicated enough, it could start identifying things that had actually been said to Alexa for training. 2) Performance: there is a lot of "magic" (I can't elaborate on that) going on behind the scenes besides simply the ML models, which cannot be easily shared.

      When consumer/public GPS first hit the market, maps were stand alone, downloadable charts. We accessed updates (or didn’t) periodically and only those we chose to download. Today’s navigation aids are live, real-time platforms capable of “seeing” closed roads, accidents, police presence, detours, etc. their coverage areas are virtually unlimited. This would never be possible with a stand alone software. Alexa is the same way. Nothing we could download in isolation would have the capability or capacity to deliver.

    A little Henry Miller. You seem a man who would appreciate him.
    “...the monstrous thing is not that men have created roses out of this dung heap, but that, for some reason or other, they should want roses. For some reason or other man looks for the miracle, and to accomplish it he will wade through blood. He will debauch himself with ideas, he will reduce himself to a shadow if for only one second of his life he can close his eyes to the hideousness of reality. Everything is endured- disgrace, humiliation, poverty, war, crime, ennui- in the belief that overnight something will occur, a miracle, which will render life tolerable. And all the while a meter is running inside and there is no hand that can reach in there and shut it off.”
