I agree with the general premise that US tech isn't exclusively in Silicon Valley or Seattle. But those regions clearly still play an enormously outsized role in the US tech industry, to the point where it seems unlikely US tech would be as globally dominant without them.

Notably several entries on your list are companies that were founded and grew successful before moving to the locations you listed, often for tax breaks and/or to fit the politics of the company executives. Aside from Dell, all the companies you listed as being located in Texas became successful elsewhere first. Texas has proved it can lure in already successful companies more than it has demonstrated it can grow them.

Which is itself a legitimate achievement, but if the question is how you grow new successful tech companies, it's not a super useful data point especially if we're taking about different countries. There are relatively few barriers for a company that grew up and became successful in the environment of Silicon Valley to move to Austin with the promise of lower taxes, but Europe can't quite replicate that same migratory model to grown their own tech industry.
