> Types solve 2% ....... Vastly understated in my experience. Even trivial python programs contain errors that could be prevented with a trivial type system like Go's And performance. Not being fast enough is a bug. Consuming much more energy is a bug, in my book. Sufficiently expressive type systems are better than dynamic typing. They prevent so many errors, especially in FP-inspired high level data transformation functions. I am saying this as a person who doesn't even like most of FP. (You can infer from my comment history).
