This post literally makes no sense. I skipped the beginning diatribe, but the bullet points as to why functional programming is an "abomination" are completely false.

FP is not bound to threaded concurrency; map-reduce is even named after the concepts from FP. Data structures can be modified by multiple threads, deterministically. Concurrency in FP is strictly deterministic, unlike most models of concurrent computation. Point 3 actually makes no sense; it's clear the author doesn't actually know any functional languages.

To be honest, the entire article is meaningless. I'm flagging it.

this is a harmful article, he's either trolling or uninformed, lots of misinformation here presented as fact with an "im smarter than you" tone. flagged.

I've been writing non-functional programs for years.

I couldn't get through the article because he sounds like such an asshole.
