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?
True.
