Noted. but responding to the “UK” comment; London is often a good guide/proxy for the UK tech scene.
But for reference: there are quite a few universities in the UK where students are learning & using Elixir for distributed/embedded computing projects so these people will gradually filter through into the workforce.
Also there are plenty of Ruby/Rails Devs who have embraced Elixir/Phoenix.
But it’s a classic network effect problem; adoption drives jobs which drives learning and further adoption. Without a big corporate sponsor like a FAANG co, Elixir/Phoenix doesn’t have the mindshare of other languages/platforms.
