"Tech" is a rather meaningless term. In any case, Tesla is much more like GM or Ford than like Google or Microsoft: They are a car company with a business that's very hard to scale. Zero chance that they become a monopoly in their space. Autonomous cars are a pipe dream and Tesla's stock price is extremely inflated because Musk has successfully convinced investors that Tesla is a tech company in the sense of GAFAM. Therefore, Teslas "move" doesn't mean a lot to California's "tech grip"
