This is yet another problem with capitalism. Since there’s a billion different brands making a billion different devices it’s takes decades for some simple change like this and in the meantime the transition period involves making a trillion little adapters that will just get tossed in the garbage eventually because either they will be obsolete or just break because more planned obsolescence.

I think this is going to change because of China. The US/capitalist ecosystem might be ponderously slow at adopting new tech into the mass market, but nothing is going to speed that up more than confronting the Collective American Ego with the fact that it’s a distant second best at something.

Having said that: high speed rail would say otherwise. It won’t change while they can keep people from noticing I guess.
