1) The language lacked hindsight in its domain because there wasn't a ton of prior art (C)
2) The language didn't have enough foresight put into it (JavaScript)
3) The language's modern usage has drifted significantly far from its original usage (Java)
Python is an example of a language people use that doesn't suffer from #1 (thanks to Perl and friends), doesn't really suffer from #2 (at least, Python 3) and doesn't (yet) suffer too badly from #3. It has plenty of flaws and limitations, but not in its foundation. The core language primitives are rock-solid.
#1 doesn't apply to Go, and it's not old enough for #3 to apply. So that seems to only leave #2.
(I should add that this doesn't make a language completely invalid or useless. I use (and even like!) JS despite its flaws; in fact I prefer it to Python overall, mostly due to the ecosystem. It's just disappointing to see issues of type #2, because they seem so avoidable.)
Your C example is also not convincing. Lisp and Algol were already strong contenders at the time. People chose C because they needed a fast and close to metal language to create their own operating system for mainframes. It was a hack just like your category 2. Still, it's a great language.
> It's pointless discussing this
I don't see how the first implies the second. This is a programming forum; it's good to discuss and debate the specifics of these things.
C may not have been the best example of the category, but I think the category stands. Rust for example, much as I love it, is exploring uncharted territory. I wouldn't be surprised if 10 years from now we have ownership-based languages that are much easier to use, simply because lessons will have been learned by that point. Arguably Java's OOP fundamentals are not as good as C#'s because Java had to explore that territory first (setting aside technicalities about what the term "OOP" really means). Etc.
I'll recommend Reddit's r/ProgrammingLanguages, as well as Scott's Programming Language Pragmatics as a reading instead. It's not fully up-to-date but I found the comparisons of features and their trade-offs in it fascinating.
If you are looking for the perfect language may I suggest Forth on a Z80? Otherwise there's going to be a pile of shit hiding somewhere.
