This is about programmers (which I am not), but speak for yourself, neurotypicals.
But even programmers should be sleeping at night. We are not some race of super humans. Even programmers feel more alert during the day.
I am not super human – or at least I haven’t found the right color of sunlight yet – but I have never felt more alert during the day. Not when I was four and not now.
It’s likely true that there aren’t very many like me, but I feel most alert between midnight to 3AM. That’s where 60% of my work gets done, and where probably 95%+ of my best work gets done.
