You're right in that you don't spend time on Haskell thinking about how the code actually executes.

But I honestly don't think performance is the reason majority of the developers shy away from Haskell. Most often you achieve relatively good performance without giving it any thought. At least compared to its peers, I mean other high level languages you'd use to solve the same problem.

It’s not a problem until it is, then it’s a pretty obnoxious problem.
