You have a lot packed into that post. It's a sort of typical Silicon Valley is the center of the Universe attitude. A few interesting things I would just point out:
Florida, like California, is a big state. It's approximately 20 million people, only about 55% of California, but economically, pretty diverse. There is a bubble in Silicon Valley, it's fairly well recognized, and it's going to pop. It's a matter of timing as to when, and luck as to how bad it will be. Many local real estate markets in California are also once again over-valued, and if/when the jobs and inflated stock market deflate, even slowly, the real estate market will be in bad shape (again). California and Florida both had big shocks with foreclosures in the great recession, however, Florida has not put the brakes on new development, which have kept new home prices relatively low.
Weather wise - I mean - you can have your pick. If you live near the west coast, like say Tampa or Bradenton - you are looking at daily average highs from about 70 in the winter to 90 in the summer. If you head down to the islands, it's a narrower band and more comfortable from the ocean winds.
Recreationally, Florida has an amazing network of state parks, and you get a nice variety of beaches - you can have white-sand beaches that are similiar to California, or you can have some amazing active beaches. Yes, there is Disneyworld, and Universal, and Busch Gardens, and SeaWorld. There's a lot to do around those things for adults - Universal for example has a pretty interesting Halloween event if you are into that type of thing.
Politics wise, is obviously in the eye of the beholder, but it's a bit weird to claim Florida is some weird political universe when you've got San Fransico in your backyard, protesting buses. Like California, Florida has a constitutional amendment to ban gay marriage, which have been reversed by Federal courts. The best comparison between California and Florida government, however, is that in Florida, the State government is basically not part of your life as an individual citizen. I moved to Florida a few years back, and I am fairly convinced that the State of Florida, except for a line item in a motor vehicle database somewhere, has no clue I live here. There is no State Income tax, nothing to file, no refund to beg for. I bought a new car, and there are no trips to city hall, or the DMV. You get a real license plate at the dealer that renews automatically by mail. And that's it. If you live in any of the rural areas, you won't have the state government in your way, and you probably have a town government either. Millions of people live in unincorporated areas, which effectively mean, you own a piece of land and pay some tax to the county, but there is no sub-division of government that makes municipal laws or regulation over you. Yes, that caters to weirdos, but it also caters to people who just want to be left alone, to live a peaceful life.
There are a lot of other positive aspects to living in Florida. We have a robust and dynamic healthcare market in most metro areas, with several large hospital groups fighting for patients. There are a many doctors who compete for patients, and keep prices low. When I shopped for health insurance last year, on the ACA marketplace, I had over 60 plans to choose from, and almost all of them were well below the national average.
Industry wise, we are more diverse in most cities than you'll find in Silicon Valley. The next wave of carnage, like the first bubble, will be epic. In Florida, we have a strong tourism sector, and companies like Mariott and Disney provide many excellent, middle class and professional job, along with roughly 250k lower-wage unskilled jobs. Educationally, Florida has an excellent University system. UF, USF, UCF are all fine universities. On top of that, there is an extensive community college network. For high schoolers, students graduating at the top of their class get free college tuition. And, it''s rather affordable. If you have a child today, you can pre-pay their 4-year university tuition for $178/month, till their 18th birthday. That will cover tuition, fees and some living expenses for any state university. There are good technology jobs in finance, banking, education, R&D, pharma, aviation, manufacturing, tourism, construction and other segments.
Cost wise, almost all areas of Florida beat California hands down. Depending on which formula's you use, Florida is 20-30% less expensive to live in than California, and depending on the area, can be quite a bit more than that as well. Utilities, food, real estate and/or rent are all less on average.
I am all for Silicon Valley, but it's not the center of the world. Florida is doing pretty well - like California there is a lot of immigration, a lot of cultural diversity (and in fact, Florida is growing population wise at twice the rate of California).
