I am a software dev. Me and everyone in my team are still fully remote. The team-lead has been backing this. Most team members would have very long commutes >1h per direction. There has been some pressure from middle management to spend time at the office. Not all teams are able to work fully remote and there is a sense those teams might envy the remote teams. But so far the software teams have been able to stay remote.
My partner is also fully remote (also a tech related job) and will remain so. Among friends and acquaintances a lot of people have returned to some office time even the other devs.
I do not think I will ever be full-time at an office again. I could imagine a job where if it wasn‘t more than 30 minutes (by bike or public transport) away I might go into the office once a week. More than that: please no.
I do have a very nice office at home. Not everyone does.
One big difference I see, between email and various messengers on the on side and social networks on the other side is, that emails are me pushing my information at people while a social network is supposed to be them pulling information from my feed. This allows me—when it works—to share stuff with people instead of potentially sending spam. Not all communication is a digital postcard. Social networks allowed a new form of communication. I enjoyed OG facebook until the first big privacy scandal. It was a (mostly) good thing and it was very accessible even then. I‘ve never got such a large part of my tribe on a pull service since then. Sure we all have messengers and groups and what not… but it is not the same. I dream of self-hosting something from the fediverse but we‘re not exactly young anymore and I doubt my tribe will assemble.
