The Difference Between Programming and Software Development?

Why learning Haskell/Python makes you a worse programmer:

So, learning Python and Haskell has demoralised me and encouraged me to write code that is bizarre and difficult to understand, and, in the context of an OOP code base, provides little benefit over imperative programming. I have no doubt that in general I am a better programmer for learning these languages, but in my current situation, I am not a better software developer - my productivity has in fact nose-dived. When I get frustrated with the C# code I write, I then go and write it again in Haskell and Python, to demonstrate to myself how much better they are, which is a pointless exercise that only demotivates me further.
