I think you may be reading more into that sentence than it says. While I don't doubt that there are programmers working 'late night, crazed, caffeine-fueled session' you're extrapolating well beyond what the author said. Do professionals work earlier or later to avoid disruptive times? Yes. My least productive period (for coding) is in the middle of the day (between 10am - 2pm). So, that is when I plan to do things that are not coding. I tend to come into work early for two reasons: (1) it makes my commute easier, and (2) I get most of my coding done before the majority of the people in the office come in. I don't think it is a controversial idea that software engineers tend to find they do their best work in quiet or low-distraction environments.

I have to confess, I do have the unusual habit of starting my day with a cup of coffee so maybe I am one of those caffiene-fueled crazies after all :)
