I agree with your the main point that there are other things to focus on besides new languages, and that these other things are also incredibly important. I could also understand why you might argue that these tools and other parts of an "ecosystem" might be more important than a new language.
But I do feel you've undervalued new programming languages. It is definitely something that can improved upon, and so we should. Computing will probably be around for a while, so if it takes decades, it takes decades.
I would say that more languages won't fix the computing world *on their own*, but are still an important aspect we can improve upon.
