If you are now a full time functional programmer, how did you get there?
There's always the issue of "where will we find people who know Scala?" of course. I can't tell if it matters; certainly, there are fewer people with that skill, but they are also competing for fewer jobs.
Later on we started a company together and went all in on Scala. It's served us very well over the quite a few years we'be been going now.
I would suggest following conferences like strange loop, for some reason a lot of speakers for strange loop work with functional programming languages
