> Functional programming originates in mathematics, which is also very human... but as complexity grows, it's not as human as you'd like it to be. A lot of humans struggle with complicated functional programming code, which is why it is not as popular. I agree, but I wouldn't say people struggle with "functional programming code", they rather struggle with the concept in general. In that sense, functional programming is like higher mathematics: it's a great tool to solve many problems in a very efficient way, but it's also difficult to learn and everyone of us reaches a level where they can't advance anymore at some point. Some sooner and some later.
