i may not have read the article correctly, but i see no actual evidence there that it is the "world's fastest growing language", whatever that might mean, except that there a lot of questions about it on SO (and of course posts like this on HN).
also, possibly related, isn't it strange you see almost no more haskell posts here these days?
the evidence is the same of the elections: if only 30% of the people vote, the most loved vote was non voting.
I don't see PHP programmers going to Stackoverflow to vote for PHP, but it still gets a lot more things done than Rust, for sure.
And not because they don't like the language, but because "normies" don't go out talking about their love for the hammer or their drill or their kitchen too... no wait, chefs talk about their knives constantly!
Sure, but that doesn't mean there isn't any evidence, as you claimed. A consistent result, year-over-year, in a large and long-running survey is definitely evidence. Not proof, but still evidence.
hn goes through phases; ocaml, haskell, go, react, ive been here almost 2 decades now and it's always been this way, but you used to be able to disagree and talk about it without being shunned by devotees. right now you're not even saying much negative but you're almost so grey you're effectively silenced.
