> Functional programming is a reaction from the shift to the dangerous quadrant of the immutable-mutable/unshared-shared "Magic Quadrant" chart.
I might rather say "The recent focus on adapting functional programming is a reaction...". Functional programming itself is nearly as old as the modern computer (McCarthy's first LISP paper was published in 1960), but your phrasing kind of suggests that the entirety of FP is a recent innovation.
Functional programming itself is really old. Practical functional programming for scale is the new trend.
What's new is the scale of software being developed right now. Developers simply can't afford to create mutable and shared state as if their program was just another desktop program, executed on a computer disconnected from the internet.
Sooner or later we learn that focusing on the human value of code (I mean, making the code clear, concise and simple to read) pays off way better on the long run rather than optimizing for CPU cycles or memory footprint.
