Jaron Lanier was a critic of the view that files were somehow an essential part of computing:

Typing on a keyboard, using files and writing on a word processor, etc. are accidental skills, not really essential skills. They're like writing cursive: we learned them, so we think naturally everybody must and lament how much it sucks that kids these days do not. But they don't because they don't need to: we now have very capable computing systems that don't need files at all, or at least don't need to surface them at the user level.
It could be that writing or understanding code without AI help turns out to be another accidental skill, like writing or understanding assembly code today. It just won't be needed in the future.
Waxing philosophical about accidental/essential kinda sweeps under the rug that it's an orthogonal dimension to practical for a given status quo. And that's what a lot of people care about even if it's possible to win a conversation by deploying boomer ad hominem.
I will lament that professionals with desk jobs can't touch-type. But not out of some "back in my day" bullshit. I didn't learn until my 20s. I eventually had an "oh no" realization that it would probably pay major dividends on the learning investment. It did. And then I knew.
I was real good at making excuses to never learn too. Much more resistant than the student/fresh grads I've since convinced to learn.
Typing was only a universally applicable skill for maybe the past three or four decades. PCs were originally a hard sell among the C suite. You mean before I get anything out of this machine, I have to type things into it? That's what my secretary is for!
So if anything, we're going back to the past, when typing need only be learned by specialists who worked in certain fields: clerical work, data entry, and maybe programming.

Writing cursive may not be the most useful skill (though cursive italic is easy to learn and fast to write), but there's nothing quite like being able to read an important historical document (like the US Constitution) in its original form.
