I think emoji would make it challenging for students. Students already struggle to decipher the handwriting and foreign notation of their professors. Adding emoji to that mix would make it even harder to keep up, and many emoji (and mathematical symbols, to be fair) are difficult to write down.

I would have struggled during my math and stats degrees if I had to distinguish between emoji and mathematical notation.

Depends on the medium people will use to do math in the future, there may be a material reason why handwriting is the main method, but I would say its just as likely that it goes the way of other, less structured texts as the tools get better.

It doesn't really matter if you can't write down an emoji if you don't write anything down.
