True.

I would point out that in 45 years ago, in 1981, the typewriter as a product was over 100 years old (first sold 1874). There was a lot of time to standardize by 1981. And there probably haven't been a lot of serviceable pre-1900s typewriters for quite a while.

The first Kindle came out in 2007. Who knows what an e-reader will be like in 2107?

I got it. And I've played a 1905 Martin and you can still plug a 1950s telecaster into a 1950s amp in turn plugged into wall power and everything works. Just saying, that is not the consumer electronics world in 2026.
