I have worked with a few developers who shared this motto. I didn't agree with them.

While it's anecdotal, my understanding is that we were simply working on very, very different codebases. I was refactoring multi-million lines C++ codebases, implementing concurrent algorithms in which dependencies cannot be expressed through language constructs and I had to make non-trivial choices to prioritize performance, or safety, or security at the expense of readability.

On the other hand, these (few) developers were working on writing fresh code, with less footgunny languages, with simpler data and control dependencies and didn't need to make hard choices due to perf/safety/security.
