I think you are right. I worked on a startup that had a few hundreds employees. Most of them in the early twenties. Every week day, a rotating subgroup of 5 to 10 of them would go to the bar after work. On Thursdays and Fridays there would be more like 30 to 80 people. I was already married, in my late thirties, so I would go home. You could tell everyone was eager to the end of the day. They were personal friends, not just coworkers.
I miss that environment, even though I was not part of the bar tradition (I don’t even drink). I can only imagine how they are feeling about working from home these days.
Remote is not a no-brainer forced by shortsighted employers like the general impression I get from HN. It is an option with serious trade-offs on both sides.
