Salaries are actually pretty good. Not facebook salaries, but good enough and certainly above average. The company can already get very proefficient, experienced developers in Ruby and JavaScript.
> moving to a better company?
I certainly could. But how does this solve the business problem I'm talking about?
The reason I'm not moving to another place and instead helping transition back to normality is because I actually like the company, and my coworkers, and I like to focus on building our product and solve the real problems the company was created for.
Elixir can be a great tech (the best) for certain kind of problems. In our case (and any other "CRUD" like web application like 80% of the internet) is an expensive, distracting toy.
So, totally disinterested question, can you name those companies paying well for Elixir in Europe? :)
Otherwise I agree with a good part of your post. For CRUD work I feel way more productive with PHP/Symfony than with Elixir/Phoenix, especially for outputting HTML. Part of it is the DX with the templating and type hinting but also the unbeatable amount of libraries and manpower behind the language and framework.
Otherwise the plugin for Jetbrain's IDEs works OK for me (but again it can't beat the Symfony plugin with PHPStorm features).
Maybe consider paying your people more or moving to a better company?
