As @neillewisjr.bsky.social said (bsky.app/profile/neil...), this is not sustainable, & we will have to do less. Academia is already rife with unpaid labor.
Again, the same courses/labs/degree programs simply will not exist, & the quality of what's left will decline. You can't have it without $.

I'm worried about this too, including given where our world appears to be headed with (over)reliance on AI (picture me: a frustrated old, yelling at the sky in futility), and what that means about what kinds of information gets sucked up into AI output vs. what gets excluded/ignored.
In general I think it's hard to combat scientific misinformation when some of the best research is locked behind an academic paywall, while lots of nonsense gets published free for everyone to read in predatory journals.
