I think there's a chance we're going to see all-remote employees be subconsciously judged on things like the quality of their lighting, audio, background, mute etiquette, etc. IMO that's a lot better than the current approach of judging based on similar appearance, hobbies, lunch schedules, golf club memberships, etc.
Being all-remote is a wonderful equalizer.
Whereas when I was in the office I saw lot of people doing mostly nothing but hanging out in the lunch-room. I guess they felt like if they take the trouble to arrive in the office that's a lot of work already. And they did not make the choice they are just doing it because they were told to do it.
I agree there is value in talking to people in person and having wide-ranging conversations about everything but there has to be a balance. But all in all I thought me working from home gave the employer much more than if I had come to office every day, and hung around in the lunch room with others.
Based on your examples, all-remote isn't an equalizer, it's changing the rules by which you are judged.
