I'm personally caught between my attachment to the "boring technology" philosophy and my desire to try Elixir, which seems like exactly the kind of obscure and exotic technology that it rejects.

I actually think elixir is the perfect boring technology now. The language is matured, and is not changing much. There will be a big addition at some point with the new type system, but other than that the language is pretty much done. Underneath elixir is erlang, which is extremely mature and highly boring in the good way. Live view might be the only exception, but even that is now becoming boring as it has gotten stable. If you are a believer in boring, you should definitely give elixir a try

Erlang is old, reliable tech that used to scare people once upon a very distant time for

- running on a VM (now boringly normal)

- using a pure-functional language with immutable terms (the pure-functional language fad has since then come and gone and this is now archaic and passé if anything)

But languages only get stereotyped once. At any rate, it's pretty boring and old.

Already said by two sibling comments in all the detail I would have, but I wanted third it: as a subscriber to boring technology myself and actually never been one to jump on new shiny tech, Elixir/Erlang is the epitome of "boring technology." Elixir does a lot on its own you can often cut out the need for a lot of other dependencies.
