I don't understand what sort of environment you work in where you don't encounter situations where comments could add clarity to the code.

Do you never see code that has global side effects? Or that is written a particular way to take advantage of the hardware that it is running on? Or any other of the many ways that the intention and meaning of a piece of code within the codebase it exists in can be not immediately obvious?

The answer for modern languages and frameworks is "write pure functions."

Move to service/helper/utility class for that particular hardware or with a name that clarifies it's for that particular hardware.

I find comments to be necessary very rarely. Atm looking at a codebase where they are made to cover up for a lack of desire to think.
