Based on the fact that you think all programming languages are essentially the same. That's just a ridiculous claim and it immediately exposes you as someone who's only used a couple of Algol derivatives.
1. I don't think literally all programming languages are the same
2. I have used Haskell, and am very aware of every language listed in the other replies to this comment, so you're completely wrong.
I kind of thought this community was better than this, to be honest.
Try saying silly things on reddit and watch the hate flow in.
E.g. "most of algol-derived languages are quite similar, aside from small differences in syntax and feature set".
Or:
"Most modern mainstream languages, etc have pretty much similar feature sets and syntax (while still differing in being dynamic vs statically typed etc)"
That's not the same as what you said.
