Meant that it enables concurrency and parallelism without having to worry so much about the mechanics of it, which helps take advantage of multiple cores as described in the article. Immutable data structures and pure functions avoid data corruption when two or more threads are working on the same data. OOP requires a lot of code to get the same result, true?

I'm new to FP myself and it seems like if done wisely it simplifies multi thread, parallel processing quite a bit.

I would check out https://github.com/reflex-frp/reflex which is truly a godsend for concurrency but actually uses loads of mutation internally.

Haskell helps loads here but the mechanisms are a lot more complex and nuanced than the circa 2000 ideology you were saying.
