Again, I'm perfectly aware of how the process is supposed to work and what purpose comments serve. This is the exact same argument people make when complaining that everybody is doing Agile wrong. What I'm explaining to you, as another senior dev in the industry, is that a lot of the time people start cutting corners because they have deadlines, or they don't understand the code because it was written a long time ago by somebody who doesn't work at the company anymore, or a myriad other reasons. Keeping comments in sync with the code is not trivial in practice, and it's often done poorly.
