Now, I'm not particularly a fan of Haskell, but I think it is disingenuous to compare it apple to apple. Most junior devs had multiple years of training in imperative OOP languages prior to joining a company. So if they join a place that uses C#, and they don't know C#, but they already know how every single feature and concept of C# works, well ya, they'll be proficient in two weeks. Similarly, had they'd been thought functional programming, some category theory, and a bit more about type theory, etc., then they'd probably be able to ramp up to Haskell in two weeks as well. On one hand, they come knowing all the concepts and only having to learn a syntax and tool-chain. On the other, they know none of the concepts, and have to learn them all as well as learning the tooling and syntax.
