It's true that Silicon Valley networking is thriving... but that does not bring businesses to the state because those startup companies place their plants and oersonnel in more business friendly venues.
I did grad school at Cal and lived in the Bay Area in the late 70s and early 80s when it was the most beautiful and liveable plase in the country and maybe the world. Now it is in serious decay in so so many ways.
Maybe that was inevitable but having a one party woke government has only exacerbated the process.
