In my early 30s here. All my friends have left, and now we are doing so, too. You are right, IMO. Most of those friends are in tech and plan to move back eventually, but are hoping to score better deals on rent then. For now they live in the mountains and can do some fun solo activities for the next year.

For us, we have wanted to leave for several years, but the ability to WFH for my wife actually makes it possible now. More space, owning vs renting, and more local friends elsewhere all are big drivers.
