>I love pure functions, but in the end, I think it is just a tool. A solution to a set of problems,

I'm tired of seeing this analogy everywhere. Everyone knows it, there's nothing new here. When we talk about things like FP or OOP, the real opinions live at the extremes. Where one tool is definitively better than another tool or where some tools are complete garbage.

Saying that everything is a tool for different things or it's all apples and oranges says nothing about anything.
