Will Covid encourage a once in a lifetime creativity surge from WFH?

For somebody, somewhere, yes.

I do know some organizations that have been forced to hire remote have found that lifting geographic restrictions can take the stress and difficulty out of hiring. Some of those organizations won't go back, particularly if there are "ratchets" in place such as being in an area with expensive office space and housing.

It will encourage lots of things, many good and probably many bad as well. It's certainly going to shake things up. I just wish I knew what direction it would go in.

Only for so long. I think people are going to burn out after a while. This isn’t a decades-long-tested means of running a society. Hopefully we will continually adapt.
