From the little I have seen, most programming language folks don't seem to care much about debugging. They care a lot about bugs not happening in the first place, which is good, testability is sometimes taken in consideration, but not much about what to do after a bug happened.

No language will prevent you from misimplementing the specs, but languages can be designed in such a way that it easy to trace back why the button is green and not red.

It seems like those who are the most serious about debugging are from the video game industry. They get all the cool stuff with time travel, hot reload, etc... So much that I expected to see something about video games, and was surprised it wasn't.
