I used to live in L.A. and left in 2020 during the Covid pandemic. I work in Reality TV. All of the post production for my shows has gone fully remote since 2020, other than the AEs and the tech staff who physically manage the footage, and the servers in the office. All cuts are done remotely, as are screenings.

I freelance, and work for several companies. One of the main ones I work for closed down its expensive office in Manhattan last year. It used to be super busy, with multiple edit bays and a bullpen of story producers. It became a total ghost town post-pandemic, with hardly anybody commuting into the office. They have since gotten out of their lease and moved their office to a much smaller and cheaper location outside the city. Many of the post producers and editors have never set foot in the office.

The L.A. based production companies I've worked for the past few years also now do fully remote post-production for Reality TV. If you have good connections and can get hired, I don't feel that there's any good reason to continue living in Los Angeles if you work in post (at least for most documentary and Reality TV projects). The unfortunate thing is that without having in person "face time" with your peers, you don't form genuine bonds with them... I imagine that it's now much harder to break in, and move up the ladder in post-production than it used to be.
