I mean, the thing is, it's not even that great a city. Like, sure the tech jobs are here, and the bay area overall is nice and has temperate weather, but San Jose itself is a giant sprawling suburb. Downtown is "okay" and we do have public transit in the form of the light rail but it's pretty slow.
I'm paying $3.4k to rent a 2x2.5 townhome with my partner currently. It's very nice, and my landlords are just a very nice couple rather than a company, but dang is it expensive just to live here.
And before anyone asks, I live here 1) because I work in tech and the jobs are here, and 2) because my family all lives in the Bay Area and they're very important to me.
Anyway, my formal recommendation to any of you looking to move to San Jose is to basically not do that. Find a remote job and work in tech that way, or hybrid so you can live further out and commute only a couple times a week.
