> I'm not saying FP is bad, it is actually really powerful when it is in the hands of those who understand when and how to use it. The problem with the attitude that you demonstrate in your reply is also not limited to FP: in the era of OOO, there were those that spread the evangelism of design patterns to all places regardless if it made any sense; before that in the 90's there was a group of programmers that liked to generate code until no colleague understood anymore what was happening.

Agreed, and what did we get? dogmatic decrying of how OOP is completely useless and objectively bad, not too dissimilar from some of the comments on FP and Scala on here.
