That, my friend, is called retirement

That calls for a group hug

Speaking only from a software dev point of view:
If the employer owns the building it is more tempting to call people back to work at the company office. On the other hand, if the employer leases some space in a building it will be more reasonable to go fully remote.
Personally I would prefer to be 100% remote with occasional meetings (every couple of weeks/months) with the full team.

This seems like the bets option for a lot of companies imo - much better for the environment and for people’s own health too (less time spent community, less stressful, etc).

I think for startups or some other companies working in a face-to-face scenario can help… tho maybe tech will help bridge the gap, with things like holograms or virtual offices that can replicate the experience authentically? (Could be a project for you Dimi!)
