Aside: I agree there is not enough mentorship, and I think a network/app for this would be amazing.
It would be great if:
a) it used LLMs to do partial AI match making
b) it had a relatively decent solution to avoiding mentors getting spammed by mentees (using existing trust networks is good except it disadvantages outsiders who deserve mentorship most)
c) it hooked into existing chat platforms so it's sticky without needing to visit the site
EDIT: I'm down to mentor on ML/AI and have in the past, for the right candidates. It's hard to put my finger on what qualities I'm looking for.
