Sure, and I still use Perl as my primary language, just as I did 20 years ago, with some forays into other languages (like Python and C) along the way. But, this is survivor bias (one could argue SQL is also benefiting from survivor bias, though SQL was the dominant data query language then and it is the dominant data query language today, whereas one could argue only C was/is dominant in its space at both points in history). But, where's Pascal, Visual Basic (or Basic of any sort), Tcl, etc.? There's dozens of other languages that came and went, including data-oriented languages. All of which were popular during the 90s, and effectively gone now. And, only C among your examples is actually exhibiting the same kind of longevity (SQL is more than 40 years old, so it predates Python, Java, Perl, etc. by quite a lot)...I probably should have put the starting point for this thought experiment at 30+ years ago, but 20 years ago is when I first started using SQL, so it's what I used, which isn't really useful. Who cares when I learned the value of SQL, when it's an industry-wide phenomenon?

My point wasn't that one can't name languages with staying power. There are several. But, SQL is still special, I think. It's almost universally needed. If you go to work in a Node or Go shop today, you're probably still gonna need to know some SQL, just like if you went to work in a Python or Perl or Java shop in the 90s.
