I'm a software engineer like 90% of HN. I have plenty of online meetings (I'm actually on a team call right now listening to someone discuss a solution to a problem). It doesn't fill the needs, though. Without the in-person and more frequent interaction, I can feel my social skills slipping even further. And I rarely interact with non-developers and non-managers now. It's not ideal for me. It 100% does not work and I need to go back to an office. I fear if I don't, my already-limited social abilities will zero out and I'll have to rebuild them. I now know I can go months without speaking to anyone and be okay with it; that itself is a problem in my mind that I need to address and an office environment fulfills those needs.
As a compromise it'd be nice once things are opened up for companies without fixed offices to subsidize passes into coworking spaces, so people can work in public areas more quiet and professional than cafes around others, but not necessarily the actual office.
