I would take this as a the thing to remember from this. When you are too angry at something, you cant learn it. I have seen the emotional refusal to learn new inferior thing (or read comments that amounted to the same) many times already.
It is something to be aware of and avoided.
I realize not everyone will have that option, but I strongly believe being strongly opinionated about what I will work with has helped me in the long run by ensuring I've actually worked on things where I could feel motivated to deliver, and letting me focus my time on getting better at the technologies I do enjoy working with.
Of course that requires ensuring you build skills in areas where you can find jobs, and that you avoid jobs where you don't get to pick the technologies you're prepared to work with.
I hated Java as everyone was supposed to in school among my peers. Java was for lesser programmers. But, there was interesting job in Java available and after using it, I liked coding in Java better then previous languages I knew (C, C++ mainly).
I've been playing "avoid those jobs" for a while now and it's getting tiresome. There is a HUGE prejudice against people who never drank the OOP kool aide.
If anything, remember that Lisp, Java, Brainfuck and hundreds of other langs are all Turing-complete and therefore equivalent to one another when it comes to computability.
This is true in a very literal sense. Emotions appear to have a very significant effect on how well we can memorize and recall things:
The new thing sucks. Or am I having a knee-jerk reaction to something unfamiliar? Maybe I'm the asshole.
The new thing falls short of the old thing. Or does it have different goals from the old thing? Maybe I'm the asshole.
Whoever made the decision to put the new thing in my path are out of touch and don't understand what I do or how the old thing helped. Or have they seen something that I don't see yet? Maybe I'm the asshole.
Sometimes I'm the asshole. Never entertaining the possibility that one is the asshole is what makes one the asshole.
So, the secret is to be alone in a room, so you can swear freely. Walk around when angry and complain to yourself. But always go back and continue using it and eventually, that phase will pass. After that you will build new set of habits that work around disadvantages and use advantages.
I experience a similar thing Elixir at times. Even as a fervent "right tool for the job" guy it's hard to have in one hand something that elegantly solves just about everything you've experienced in your career...and not be able to use it.
Between Elixir and Python, there's not much of a need for anything else on a server these days.
Fortunately for me, my rage at Fortran came after I mastered it.
