As a counter point: I have simple node scripts, that serve the same purpose to me. And there was also the need to fix something 2 days ago in an 8 year old script. Opened the file, changed the code and running it again. Took 5 minutes and it just worked.
I don't use js because it is the hot new thing, but rather because it is simple. (But I avoid messy and obscure npm repositories wherever possible for example.)
Hm, video arguments are not my take, I did not watch it (yet), but in either case this seems to be opinion.
But of course, javascript is so simple, that it is not suitable for complex problems. No (sane) person would ever claim, that it is the right language for every problem.
I am suggesting that you are making exactly this kind of fallacious argument when you say “No (sane) person would ever claim, that it is the right language for every problem.”
People always underestimate how stable JS is. I would argue that it is more stable and backward compatible than a lot of backend languages. What is not stable in JS - is a whole ecosystem.
