In math, expect it to ne a mess, mostly because nobody is worry about industrial espionage[1]. Some researchers may get an AI version bought by the university, or school or department, others pay from a grant or their own pockets, other use the free version.

I still remember 2020. We (I, my wife and a few close friends) got in total like 5 Moodles for math inside the same university, and I'm not counting the Moodles for physics or other subjets, and probably there were a few more for math that I didn't know. Each one has a slightly different configuration, so it was a mess to teleport info.

Same with email, we have a different email server at the university/scholl/department level. (Who knows how Gemmini/Copilot/Whatever is configured in each one.)
