Ocean access, proximity to Asia, and natural spaces are found up and down the entire West Coast. Access to nature is considerably better in Seattle than the Bay Area, for example. Most world-class universities on the West Coast are in California but Washington also has one.

The main advantage of California, from a tech perspective, is its large and mature ecosystem, which isn't intrinsic. San Diego does have uniquely perfect weather but that does not extend to the rest of the State and no one goes to San Diego for tech.
