I won’t go that far…yes, the West Coast of the US is dominant, but it’s not “literally the entire tech industry” or even figuratively. We’d have a hard time buying new hardware without Chinese and Taiwanese companies. South Korea is a powerhouse in consumer tech; think Samsung and LG. Japan doesn’t have the dominance in tech it once did, but Japan is still a major player with many large tech companies like Fujitsu, Hitachi, Sony, NEC, and many more. Plus, if “tech” isn’t limited to software, then there are plenty of players worldwide in biotechnology and automobiles.
And let’s not count out Europe. I’m actually typing this in a BMW dealership’s waiting room in the Bay Area as I get my brake pads updated. BMW definitely qualifies as technology, even if it’s not a software company.
But, notice how all of the core manufacturing capabilities you just mentioned weren't from European companies either.
It may not be accurate to say we have the entire global technology landscape, especially after the sellout of our manufacturing base in the 70s and 80s to Asia, but it's not exactly like Europe has it either.
