My guess is that established companies (esp. those with existing offices) will require on-site work, new companies without will more likely not... more flexibility for founders and reduced costs if they believe in remote.
That should leave everyone with plenty of options, but on-site + startup combo would have fewer positions and vice-versa remote + established company.
Otoh, over time I could see a profound shift to remote if these new companies were to start replacing old ones and remote worked for them. But there might be a limit where a certain company size favors on-site.
Unfortunately the best work experiences I’ve had are in micro-small scale startups in SF/NY where I walk to work every day, sit in the same office with a couple/handful of people who I know are passionate about the same problems I am, and we all have the opportunity to brain-dump in person at will. Arraigning zooms will never compadre to the fidelity of a face to face interaction.
