For example, while for many Elixir has been a 'step up' from Rails, most advice given, even deep in Elixir land, is that Rails might still be the preferable choice for a variety of reasons.
I imagine part of the reason is that most of 'us' don't use Elixir exclusively, so we can't just bail out of all other ecosystems and do the whole us vs them thing.
On the other hand, the above commenter seems to actively go out of their way to comment negatively about Elixir whenever it's mentioned on HN, and I still don't really understand why anyone would put in that kind of targeted effort.
