I don't have any proof or even tangible evidence of this, but anecdotally I wonder if, even though Seattle has a lot of tech workers, they're a self-selecting population of tech workers who don't want to be entrepreneurs. I'm in Seattle, and I've worked at Microsoft, Amazon, and a couple of smaller companies, and I've run across quite a few people who could've gone to either Seattle or the Valley, and deliberately picked the former because they didn't want to participate in the startup rat race and just wanted a stable job. And of course, this trend would be a positive feedback loop over time: the more the Valley is associated with entrepreneur culture and Seattle is not, the more that potential entrepreneurs go to the Valley and the day-jobbers go to Seattle, which reinforces the original perception. Again, this is all guesswork, but it does line up with my anecdotal experience.
