Scala. When I started learning Scala, it was such a breadth of fresh air and I enjoyed it. Cut to 5 years later, it offers so much flexibility that using it in a team results in significant overhead and becomes very easy to introduce unnecessary complexities in the code. My personal experience has been that proficient programmers in Scala are more into the language than the product that all they want to do is refactor the code with next strongly typed library (scalaz, cats, akka streams to monix). Combine this with not so involved manager, it affects the team dynamics and not meeting deadlines regularly. I don't see the language itself as an issue, I do like Scala but it is one of those languages where one can try to do the same thing multiple ways again and again that there needs to be a strong guidance and captain to steer the team and keep course.
