This is ridiculous. The Bay Area, specifically Stanford and Berkeley, contributed to the WWII tech research initiative and then afterwards, Terman made Stanford Research Park which led to Silicon Valley.
Without William Shockley moving to the west coast, the "Silicon" part of Silicon Valley would likely be elsewhere in the world.

Many many many companies tried to move the industry away from California since the 50s, and every time, those companies star players ended up relocating to the bay area.
