After watching the latest Veritasium video about how Newton figured out a novel approach to solving PI which was dramatically simpler than the previous thousand-year old methods, I wonder if someone will come along and figure out a simple mathematical way to break these encryptions. That would be horrifying of course, but also really cool.

That video was one of the best videos on mathematics I have ever seen; the visualizations to aid in the explanation of Newton's "new" algorithm were absolutely top-notch. I'm not sure I could have followed it without them. With them, I feel like I know it well enough now to explain it to someone else.

The thing with applied cryptography is that everyone is expecting the attacks to get better over time, sometimes in big and inconvenient bursts. There are several strategies to mitigate this, including oversizing security margins by a certain amount (so that an innovation that improves an attack by an order of magnitude or two isn't an instantaneous shattering of your whole security model), and having what's sometimes termed "algorithm agility" (which has somewhat fallen out of favor recently due to having its own class of bugs due to the implementations around, say, an optional NONE pluggable cipher type).

Check out 3brown1blue if you haven’t already. The animations are excellent.

3brown1blue is also the creator of manim, the library used for his own videos: https://github.com/3b1b/manim.

It's an awesome python library to create math animations, I would highly recommend it.
