My anecdotal observation is the opposite. It seems like since Covid, demand to live in big cities has gone up much faster than before. You can mostly see / feel this in property prices.
Yeah, small data point, but everyone in my circles who tried "remote life" realized why they're not fond of it, moved back into cities. It's not for everyone, and it's definitely not for me. Giving up walkability, being surrounded basically endless amount of options, and the ability to get away if I want to is a no-brainer for me.
