If the libraries worked, we wouldn't have had to play code archaeologist and find out that half our dependencies had been abandoned since 2017. Even something as simple as a JSON encoder--which is rock-solid in every other language I've used--had a number of bugs (this was four years ago, so memory is hazy, but it had something to do with ambiguity between arrays, lists, or tuples) Erlang is stable, but Elixir sure as hell isn't. Back in 2019, it seemed as though every point release brought a slew of breakages--and usually over the most trivial and pointless things, like adding an underscore to a built-in for "consistency". I've been developing for over 20 years, have used all of the mainstream languages, and Elixir was the absolute worst.
