Well, we have FP at home.

It just got ingrained into pretty much every mainstream language, and most [1] of the wins can be had even when it's applied to certain parts of the code base only. Like, Java has immutable data classes (records), ADTs with pattern matching, etc.

As much as I like Clojure, I just don't think Lisps can ever become too mainstream, their readability simply repels too many people (and even though I am okay with reading it, I do think it's less readable than an equivalent Java-style code would be).

[1]: I would even argue that a properly mixed pure and (locally) side-effecting code is the happy ground, as they strengthen each other
