My wife and I are not in the tech scene. I am a marketplace founder and she's a Big Law attorney (real estate). We're in our 30's. I'm less concerned with the tech scene and more with the overall startup/entrepreneur community.
Finding a job is not a huge concern for either of us. She'll be fine anywhere she goes and I'm sure I can find something remote if my startup doesn't succeed.
I think our main concern is around culture and community. We like to party and be in the "scene" but also plan on having kids soon(ish). Our current circle of friends in Boston is small but they're all very educated and great to spend time with. They're all in finance, law, or entrepreneurs. One of our worries is that it'll be harder to find those educated but fun people down in Miami area. Maybe this is totally wrong. This may sound crazy but the concern is that the people down there are either South American millionaires, bottle girls, OnlyFans, etc...haha. I know it's a huge stereotype of FL.
Again, really appreciate all the thoughtful comments here.
