I agree :-)
Ruby is alive and well, Python had a surge because of data science, AI and ML, Java is alive and well (maybe less adopted by new Android apps, that's it). All of three are quite old languagues.
It's really really hard to effectively measure "obscurity".
Perl is the perfect example, I haven't heard about it in years, it's not the cool tool everyone is talking about anymore but it's not dead either.
We're a place where coders share, stay up-to-date and grow their careers.
We strive for transparency and don't collect excess data.
