> I wonder what the 2026 equivalent of going to California is now, if such a thing even exists or can exist.

I think this becomes increasingly difficult, because the timelines become so short with almost-instant information desimination, higher inequality and increased mobility for everyone. A place or event can go from underground -> awesome -> gentrified -> 'dead' in a manner of a couple of years now.

I live in a neighborhood that is currently being gentrified; 10 years ago no non-local wanted to live here, 5 years ago, it was the place to be, today young/hip people are beginning to move elsewhere again. Newly rented-out flats are now thrice as expensive as 2020, and you can see in real time how bars and restaurants are replaced with more expensive alternatives. When I compare this with other neighborhoods in Berlin (eg. Bergmannkiez or Kollwitzkiez), the timeline has roughly halfed.
