Yep, I like the current trend where remote jobs are becoming more common so you can live in the Midwest while employed by a high paying SV/NYC/etc job. I don't really need the cultural elements of SV being spread across the US, that's part of the whole reason why I love the Midwest to begin with.
You don't know what you're saying. They'll bring higher home prices, more traffic, Californian politics, complaints about the weather, snide remarks about how things are better in CA. What's not to love?
Just ask Coloradans, it's wonderful to have your state taken over by people who don't share the same political culture, have far more money, and don't care much about land use!
