I've been permanently remote since 2014 (with some regular office visits interspersed at a few employers along the way). My take is that working in an office is superior to working at home, so long as employees have short commutes and the office provides an environment which is conducive to productivity (e.g. private offices or well-made full height cubicles). In any other situation than that (e.g. open floor plan being the worst), remote work is massively more productive than time spent in office.

It does require a cultural shift in an organization, and I do find that companies that are half-remote/half-onsite or some mixture tend to do significantly worse than companies that go all-in on remote or all-in on staying in the office because the mix always leads to remote folks being left out of important political nuances handled in the hallway and break-rooms.

I don't see myself ever working for Amazon for a myriad of reasons (or most of the other FAANG companies for that matter), but I do think this issue is more complex in a large organization than many WFH advocates give it credit for. That said, I never intend to go back to an office other than for occasional visits for the remainder of my life/career.
