I think the likely outcome is going to simply be more mix of remote and onsite in the future. Any company that makes it through this is going to realize remote works fine. I'm sure there will be some companies that will still insist onsite-only, and they'll lose a bunch of employees who just realized they prefer remote.

Regardless, what I really hope is that at the least this helps companies shift towards more remote-friendly culture and policies. Things like: every meeting has a conference link; one person remote, everyone remote; more async communications and decision making. If you do sit in a room together, have some empathy for remote people, and make sure you have high-quality video and audio, no tapping on the table or "side-conversations" while hovering over a mic, and make sure you have remote videos feeds visible and are sharing the screen you're discussing.

It would be great to see a list like this amended to include how this type of thing is handled at the company as a whole (eg top-down, global policy as opposed to varying by individual teams/managers) - like a "remote-friendly" ranking scale, or maybe a "Joel test".
