I wanted to point out an article called Why learning Haskell/Python makes you a worse programmer.
When I found the link in my aggregator, I was expecting the worst, but the title is just gratuitously incendiary. The actual article is thoroughly reasonable. It asserts that learning better languages will make your day job an excercise in demoralization and then asks the question: if you’re a C#/Java developer in the trenches, how do you benefit from your broadened horizons?
There is lots of good discussion in the comments; don’t skip them. What there is not, unfortunately but unsurprisingly, is an easy solution.
