Wow - so many old-fashioned opinions here: Just go back to how it was before COVID. Continue to kill the climate, waste lifetime in traffic jams, let germs (you don’t believe this was the last pandemic, do you?) have a party in public transport and open offices …
Getting together in a central space for work was mainly an invention of the Industrial Age. We are now in the Information Age. Many jobs are location-independent and computers and networks are powerful enough to allow for a modern workflow, which is not necessarily locked to a central workplace anymore.
Sure, it gets more difficult and complex to manage a distributed team, but hey: Reality is that more and more teams are already multi-locational anyway. And all these theories of people connecting in open spaces can only come (and be supported) from people who don’t sit in such open offices themselves.
Reality is that an open office is loud and people come by for just a chat, without asking whether it would suit you currently. Perhaps those chit-chat people are the loudest advocates for returning to the offices, I don’t know.
And commuting is another huge issue: The “we always did it this way“ is so boring! Yes, we did it and probably the vast minority was happy to waste time in traffic jams or generally in commuting, just to come to the office.
Driving a 2-ton SUV to transport 80kg of wetware (a.k.a. a human) from A to B is a thing of the past. There are studies about the positive impact on the climate when suddenly individual transportation went down massively, with many people working from home.
Many business travels can already be avoided by modern communication means (sorry folks, no more company-financed parties abroad) - and office work is the logical next step. It may not suit everyone for various reasons (e.g. space or self-discipline as well as company interests), but for those who want (and whose workplace/tasks allow for it), a modern company should offer the option of up to 100% working from home and organize the necessary infrastructure.
