O_o

How did you manage to put these two statements in a single sentence implying positivity :)

Why do people choose to explicitly write unit tests over and over again for basic things which could be caught by a compiler?

People are losing so much productivity (both short and long term) and being deceived into not having the type system "stand on their way" while they're typing out the initial prototype. This always bites back when you start first significant refactoring.

I will never understand the appeal of the dynamically typed language. Modern, statically typed languages with strong type systems, provide so much more productivity, reliability and confidence in the codebase that it is really irresponsible to ignore them nowadays.
