I know someone who became mentally ill when the bootcamp switched from in-person to remote and had enough stress to develop schizophrenia from the stresses of trying to apply for jobs remotely and alone in 2020.
There's downsides to both. When schools switched to remote I was able to travel home and study next to my partner, instead of being in a depressed state on-campus.
I think the general rule is that going remote increases variance.
That can be good when it lets people tailor their environment to their own peculiar interests. And it can be bad for people where the normalizing environment of a shared social space helps them drag some deficient attribute back up to a healthy level.
