In NYC, certainly seems like there is a fresh influx of former SF residents. Many around crypto / fintech as all large banks are here.
Refrain I often hear is that "street culture" is dead in SF. Tech workers just stay in and order Seamless and tinker on their respective inventions all night long. Although nowhere what it was at peak in 80s and 90s. NYC nightlife is still popping ;)
I'd also be interested to hear about life in the Peninsula. Hills above Palo Alto, San Mateo, even South SF. Family and friends seem to love it despite chilly nights in the summer...
