Why isn’t Oakland Silicon Valley North?

In any balanced, rational world, the City of Oakland would comprise Silicon Valley’s northern boundary. Oakland is right in the geographic center of the Bay Area. Of the entire nine-county region Oakland has the best network of freeways, rail lines, shipping ports, bridges, public transit, and every sort of infrastructure. Access to U.C. Berkeley is a top draw for tech companies, as Stanford was in the early days of Silicon Valley.
