This principle implies the C programming language will outlive Rust, Go, Python, etc. I'm not sure how I feel about that. There's a good chance its right, but I'm uncomfortable imagining my grandchildren learning C's weird quirks.
There's definitely codebases written in C today which will outlive me, like the Linux kernel. And most of those codebases will probably never migrate to a different language.
The question of whether a technology simply exists vs. whether it retains its popularity is an interesting one. Chairs and forks will both exist and be popular. iPhones will exist, but they won't be popular on some time scale. So it is interesting to think whether C is closer to one or the other :)
In any case, I'd argue that most of the quirks are due to undefined behaviour as implemented in the compilers. And 50 years from now the language have probably evolved some more anyway.
I learned Dvorak a decade ago and loved it unless someone else had to use my computer or I had to use a shared computer. I'm typing this on a qwerty keyboard and I'm okay with that now.
Typewriter layouts are designed to avoid jamming, but not by reducing typing speed. They place letters that are pressed in direct succession apart, so that the levers don’t collide. Trained typists can write pretty damn fast on a typewriter.
... and that really reduces typing speed. When i switched to dworak I was amazed how my fingers just roll on a keyboard, forming sentences faster than I even form a conscious understanding in which succession should I move my fingers. It just happens as if by itself!! Just think of a word to type and it is already on the screen.
That may be the effect for you, but it's not a goal. It's maybe a tradeoff, but machine writing is a trainable craft. Usual results for trained people are at about 200 - 400 characters per minute measured over 10 minutes. Championship results are at up to 900 characters.

I've always wanted a Blick, their "scientific" DHIATENSOR layout intrigues me. They also made a qwerty version and I seem to remember a story that their salespeople would make you sign a waiver that you were choosing a less efficient keyboard if you bought one. That's certainly 90% marketing for their layout and maybe 10% fact, but I find it amusing (if true, but I can't seem to find a reference to it any more).
I'll bet typewriter-trained typists can really move. It's definitely a separate skill, at least for the manual typewriters in my collection which have about an inch of key travel and a heck of a lot more actuation force than the gateron red switches I use at work. :-)
Ultimately I find that the fastest layout is the one you know.
Dvorak has specialised right- and left-handed layouts. Maybe it also needs specialised one finger layouts, too.
I can imagine you'd need to use both thumbs extensively or you'd be jumping back and forth. I definitely found that when I was laying on my side on the couch, propped up with one arm, qwerty was easier to use with one hand. Not that that's an ergonomic or sustainable way to type, but I was a lazy college student and I didn't care.
What about them learning English's even weirder quirks? Does that make you uncomfortable as well?
I have come to the point that I sort of accept C's quirks, and, with the appropriate mindset, I can even love them. I certainly see myself as an old man teaching these arcane quirks to a young and innocent audience.
And COBOL is extremely niche, while C is still quite common and useful to know.
Certainly higher-level languages have edged out C in many domains though.
