Always keep in mind: lies, damn lies, and statistics ...
Ruby is a little bit on decline, at least on StackOverflow: insights.stackoverflow.com/trends?...
In comparison, look at what happens if we add Python insights.stackoverflow.com/trends?...
Indeed, and I don't really have the impression that Ruby is already partway fading into non-existence (as the graph somewhat suggests, given the decline and the general low absolute count itself). As to Python, in the graph it has overtaken Java, and completely overshadowed most other languages that I tried. Taking the graph at face-value, it would be reasonable to expect Python to be the only real game in town, but that surely isn't the case.
And that's my point about these kinds of graphs in general. As Inigo Montoya would say (if he were a statistician): I don't think that graph means that you think it means.
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.
