Most proponents would say it helps you write bug free software or to write software in a cleaner way. I&#x27;d agree with that, and even say it&#x27;s much more fun than other languages I&#x27;ve used (Python, Java, Ruby, etc).<p>But in the end I don&#x27;t think it actually enables us to do anything that we haven&#x27;t been able to do before, so it&#x27;s probably not as significant as Deep Learning in that respect. To be completely honest, I am not convinced it has huge practical application, as I don&#x27;t think it will ever be picked up by industry in its current form.<p>The reason I don&#x27;t think it will be adopted by industry is that a company&#x27;s concerns are typically not really aligned with a programming language researcher&#x27;s concerns. For example, a company probably wants a language that is easy to hire for and easy to train for, and Haskell is definitely neither of these things. Also, from what I&#x27;ve heard, it&#x27;s very difficult to debug and benchmark Haskell programs, perhaps due to its laziness.<p>Take all this with a grain of salt though as I&#x27;ve only been learning it for 1 year and read the majority of two books on it; I&#x27;m far from an expert.
