Wait, I'm curious about this bit - I did my math undergrad ~16 years ago and all my homework was handwritten.

Are now AIs capable of ingesting my mess of poor handwriting with arrows indicating the flow of a proof (e.g. from the bottom of the page to the top of a hand-drawn column half-way up the page to cram in the rest of the proof)?
