I've always thought the basilar membrane was a fascinating piece of biological engineering. Whether or not the difference between its behavior vs FT really matters depends on the context. Audio processing on a computer, FFT is often great. Trying to understand / model human sound perception, particularly in relation to time, FFT has weaknesses.

Learned about the tonnetz (among other models) from the book "Audacious Euphony"... Challenging (and unfortunately too expensive now), but fascinating stuff...

This one is actually more sophisticated because it doesn't rely on scrolling pixels like the OP. So the object doesn't just disappear in screenshots, but also when the animation stops moving! So you can't actually display text that stands still, like the "hello" in the OP.
Yep. He tries text in another video by flipping pixels for one or more frames, so the words disappear very quickly. Definitely harder to read, especially longer words: https://youtu.be/EDQeArrqRZ4

Others have mentioned Branta Games, but I first saw the effect here: https://youtu.be/TdTMeNXCnTs

I don't think this is really a problem. The general problem of finding a proof from some axioms to some formula is undecidable (in e.g. first order logic). But that doesn't tell you anything about specific cases, in the same way that we can easily tell whether some specific program halts, like this one:
"return 1"
True, I was rather pointing out that being able to parse symbolic language deterministically doesn't imply that we could then "reason" deterministically in general; the reasoning would still need to involve some level of stochasticism. Whether or not that's a problem in practice depends on specifics.

I'm pretty much a layperson in this field, but I don't understand why we're trying to teach a stochastic text transformer to reason. Why would anyone expect that approach to work?
I would have thought the more obvious approach would be to couple it to some kind of symbolic logic engine. It might transform plain language statements into fragments conforming to a syntax which that engine could then parse deterministically. This is the Platonic ideal of reasoning that the author of the post pooh-poohs, I guess, but it seems to me to be the whole point of reasoning; reasoning is the application of logic in evaluating a proposition. The LLM might be trained to generate elements of the proposition, but it's too random to apply logic.
Problem is, even with symbolic logic, reasoning is not completely deterministic. Whether one can get to a set of given axioms from a given proposition is sometimes undecidable.

Hmmm... Nothing made me cry. I will diminish and go into the west.

Ha! Fun stuff. While some ideas are actually intriguing, many if its suggestions seem to be overly vague jumbles of common phrases and technology. "AI-powered databases to leverage personalized accessibility for team management..." Lol. Still fun though.

You are 100% correct. It turns out that I am an OK engineer, and a terrible marketer. There is a LOT that I need to improve on the site and the videos.
Some little audio examples would also be nice so visitors don't have to scroll through the video to hear them.
Still, awesome work!
Christmas 1996, I was 11. We finally got a modern computer with Windows 95, a CD-ROM drive, speakers, Oregon Trail 2... It was magical! The only time I ever wept with joy over a Christmas present.
