Classic "Silicon Valley" did not included San Francisco. SF was a city an hour north of Silicon Valley but never part of it.

I guess by now I'm an "old timer" Silicon Valley-ite (been around here from early-mid-90s), but I still have a cognitive dissonance when thinking SF is in any way part of Silicon Valley. But yes over the last decade+ it surely is.
