Tech jobs in Italy are ok, the only real tech hub is Milano, and the pay is fine, not high as other EU countries, but the cost of living is also lower, while I think the quality of life is better (based on my priorities). There are good startups (especially in Milano), but I think the majority of the companies are still with an oldschool mindset, so that might not be too attractive. I know of a lot of companies that I would be glad to work for, with agile mindset, nice culture and good technology stacks, but they are maybe 5% or less of the all the software companies.

I have learned Elixir about four years ago, coming from Ruby, and haven't looked back since. Of course, when the domain or the nature of the problem at hand requires different technologies, I use other stuff (python, c, go, etc.), but for most of the stuff I work on, I find Elixir to be a great fit. I don't want to go in too much detail, but if you're considering learning Elixir to find a job, you won't have trouble finding jobs, but other languages might get you there faster and open more doors. If you want to learn a new technology that will influence the way you develop and think, and show you a whole new way of solving some problems (I can't stand concurrency in any other language after working in elixir/erlang) I think Elixir is a great choice.
