Ask HN: What are specific tangible benefits of learning Haskell?

I've worked in C/C++ for many years and recently started trying to learn Haskell. As many new people learning Haskell, I am running into issues with not just the quality of learning material but the general attitude of members of the Haskell community. For example, when asking for an explanation of a particular topic recently, I received a barrage of insults about how annoying it is for people to be asking such questions, short unhelpful answers without explanation, a near constant refrain of "ask this question on IRC" because apparently people cannot be bothered to answer questions outside of there, answers which do not actually answer the question raised, various forms of pats on the head and patronizing "You go ahead and think that, Timmy. You'll soon see how wrong you are" styled answers, etc., etc., etc. Some members of the community have been nice but the more abrasive members have left a sour taste in my mouth. Is anyone ready, willing, and able to provide clear and concise explanations of specific tangible benefits of learning Haskell? I've spent almost 6 months trying to learning the language and I really don't feel like wasting another 6 months if it's not worth the effort in the end. If making objectively verifiable arguments, like "functions are more concise", please provide proof of claim.
