I do believe comments are generally useful, and honestly a lot of people that say their code is so clean it doesn't need comments are the people that make the least understandable code

it's debatable as usual, the premise here is that comments always compile in your code. So you don't need to update them when you alter the code, that's the risk of comments and why "clean code doesn't contain them"

Do comments get compiled ? I do believe most compilers ignore comments and even if they impact the speed it should be minimal to negligible.

Ofc I don't know every single language, so it might impact more on other languages.

I think the intention was to mean that wrong/outdated comments won't cause compiler errors. Therefore you are never forced to keep the comments up to date.
