I am unsure if this is a common mindset for Americans, but I personally perceived Europe as rather backward and out-of-date, technologically. I don't know why I got that idea, other than "Europe is more ancient than us" and believing that USA is the nexus and origin of all innovation.<p>So, when I arrived in Barcelona and Catalonia, I was pleasantly, mildly surprised that not only had Europe kept pace with us techno-mages in America, but they had some kind of parallel evolution going on, in terms of connectors, interfaces, protocols, etc.<p>My fiancée was sort of mystified, because my favorite subject of photography was not landmarks or her pretty face, but the circuit breaker box, the rear of her television set, the A/C unit, and any other cool, distinctly Euro-tech instances I could identify around there.<p>I tried helping her adjust/fix her aerial TV antenna, got zapped a few times; discovered that Catalonian TV antennas are energized with a few volts for whatever reason; decided that Euro-tech is beyond my expertise to tinker with on someone else's behalf, especially a native family.<p>Thankfully, I didn't have any portable electronics or appliances in my luggage that needed adapters or plugs, but the experience was truly humbling, and eye-opening, and I returned to the United States with a better calibrated worldview.
As for the TV antenna, centralized European installations tend to have really long cable runs, even more so for cable TV, and there's a wideband PA in the basement.
The US technology advantage is in software, hardware, biotech/pharma, AI, some advanced robotics (China is leading in general robotics), quantum, aerospace, military, medtech.<p>Competitively the US does well in energy tech and agriculture tech. The US is #2 in wind power, #2 in solar power, #1 in nuclear power, along with being the world's biggest oil & natural gas producer. The US industrial rail system is also an epic scale marvel, while its consumer rail system is pathetic.<p>It's definitely not elite in most infrastructure (including electrical plugs).
