It's just at the peak of the hype cycle. Other languages/technologies have gone through this in their day - Node.js and Go come to mind. Eventually it settles. No doubt the advent of some new hotness would catalyze the process.
There is also very bad moderation from HN moderators. Almost every thread discussing C/C++/Go is quickly spammed by Rust evangelist. Which makes it hard to discuss news about those languages.
If you'd like to help with that, you could let us know at hn@ycombinator.com when you see offtopic or generic tangents. We downweight those when we see them, but we don't come close to reading everything that gets posted here. There's far too much.
What are Erlang days for?
Erlang days are where we live.
They come, they wake us
Time and time over.
They are to be happy in:
Where can we live but Erlang days?
Ah, solving that question
Brings the priest and the doctor
In their long coats
Running over the fields.
