Oddly enough, being a superior language isn't the same thing as being a language anyone actually wants to use. There's a reason Python and JS are some of the most popular languages in the world despite "superior languages" existing.

I suspect that most of the ones I name will join the bone pile of the many other "superior languages" or continue to be used at most by a niche few.

something else will come along that's even more superior, and the tooling surrounding your once-superior codebases will bitrot as the community jumps onto the next passing ship and you're caught holding the bag.

Betamax and HDDVD were superior too.
