    I have a computer engineering degree and 10 years of work experience but I find your videos so amazing that I find myself watching them even about things that I already know. BTW I was so fixated and hypnotized by the way you move the mouse cursor and how smoothly it's done that I had to backtrack a section of the video several times because I was only paying attention to the mouse hahaha you make it seem so effortless like "I'm recording my screen just moving the mouse and talking" and I'm not sure but I'm under the impression the mouse is scripted or smoothed (great work! That's very hard to achieve and takes a lot of work and attention to detail). Anyway, your video is extremely easy to follow, and that's a huge and great thing because there is an immense amount of people trying to teach these concepts and yours has definitely stood out as the best, most beautiful, and easiest way to learn.

    Hey Sebastian. I know I'm 2 years late to the party, but I just recently discovered this series of yours, and following along has been a blast! I'm curious by nature and have always wanted to understand fundamentally how computers work, so upon discovering your videos and the simulation tool you've made available, I knew I'd struck gold. I've sunk 10s of hours into grasping how each logic gate works and how stringing them together can eventually result in a functioning computer. I haven't even gotten to the later videos in this series, but I've already learned so much that I want to thank you for doing all of this. You're amazing!

    Both of your videos on computer science have been amazing. So clear and easy to understand (though it took me much longer than the video time to digest everything fully and create the same components in the simulator for myself and truly understand them). I really do hope you'll make that next video you promised, but even if not, thanks so much for what you've done so far!

    The history of how computer memory has worked over the years is pretty fascinating. Early on it was a real struggle. Of course the vacuum tube and transistor circuitry in early machines had "state," and that's a form of memory, but it's a very small amount of memory. Large capacity memory was a challenge. One of the first early "sizable" data storage methods actually used a phosphorescent screen - you could whack a spot on the screen with an electron beam and it would make it glow for a period of time. Then a network of light sensors could be put up against that that let you "read" a spot on the screen. You had to refresh it before the glow faded to keep the memory intact. I don't remember the name for that method at the moment, but it was used in early machines. You could get a few thousand bits of storage this way.
    An early 1960's electronic calculator used a coil of piano wire that would carry torsional vibrations from one end to the other in a wave-like way. They'd "twist" data into one end and could read it out again a short period of time later at the other end. That was the calculator's memory.

Just one quick suggestion for the sim: Make players able to delete chips, preferably by right-clicking, which would bring up a small button to delete. I made a 4 bit adder, but then realized if I was to ever use it in even bigger calculators, I would need to add a carry in input (something I neglected to do). Now I have two adder types, and the first one isn't worth having, but here I am.
