> animations to explain highly technical ideas

Do you have an example slide? Just trying to understand what you mean.

Yeah, this illustration is what can be done in PPT in 5 minutes to explain how adding more layers/data can filter noise from signal, when I don't think it will take 5 minutes for me to write a LaTEX code that does the same. That's not counting Powerpoint does allow me to draw lines and stuff easily on a canvas. If I want to do it in LaTEX, I probably will need to draw that diagram on a separate program and import it back.

Sorry, the slide is clipped for some reason, but that's because I don't know how to configure OBS. It's not the best illustration ever, but you probably get the idea.

Here is an animation that isn't mine and I think it's really well done to explain a hard idea (not necessarily in PPT):

I agree. I've given talks on pretty math-heavy ideas but they can still usually be explained visually in a way that is significantly easier to understand without losing fidelity. I love LaTeX and Beamer for pure text/math, but once you want animated slides, or even including videos/gifs, PDF gets flaky fast. Keynote and PPT are pretty powerful tools.

(also, the 8-bit guy is great!)

Steven Wittens have written about this and his MathBox^2. I've never used it, and from the examples it looks like it might be too much work for most presentations to be worth it, but the examples are pretty impressive.

Oh, I'm already completely convinced about the expressive power of animations. Just wasn't sure how much is possible with PPT/Keynote. Could 3Blue1brown videos be made in Keynote? But I can definitely see your point. :-)
