If you are doing a "startup", there are benefits to being near SV for the VCs and talent who want that life. If you are just wanting to start aomething new and not seeking the YC/VC model, choose whichever town makes you happy.
What I expect to change over the next 10 years is an increasing number of people making the latter choice.
For me, India is one of the best place as it has a HUGE online population, growing spending capacity, quite a large number of huge problems to be solved (for e.g. there isn’t even good Adult ADD care available in India in 2020, many many more probs) and a good number of decent tech workers (rising number of great tech workers).
A lot of investors, including Sam Altman, have said that SV isn't the best place anymore. It's not worth it for them to move out, but I doubt they'd do SV now if they had a choice. SV was popular because as Paul Graham said, everyone was optimistic and always smiling, but this really isn't the case anymore.
No income tax on business or personal income. You can become the state’s resident after spending just one night in a hotel and opening a bank account. That’s partially why it’s highly favored by RVers who choose to longer have a permanent home.
There’s opportunity to modify the state’s politics. ;)
