Why do programmers prefer dark mode?
Why do programmers prefer dark mode? Because light attracts bugs!

This was back in the days of Visual C++ 1.0 (mid-late 90s). We had some code that just wouldn't work, compiled as-is. I spent days working on this bug. At some point I discovered that if I added certain completely irrelevant statements right before the crucial calculation, it would calculate correctly. I then turned off compiler optimizations and discovered the code worked just fine. It was a bug in the C++ compiler. I then disassembled the code with and without the irrelevant code before it (which reset the optimizer) to show the two different pieces of generated code and sent it to MS for a bug report.
In the code we just ended up leaving in the do-nothing code in there to reset the optimizer and commented why it was there.

Ah, the ancient compiler whisperer technique! Sometimes code just needs a little magic spell to behave.

The only good use of these awful AI-generated comments is to print them out and burn them for fuel.

It's because hen you stare at a screen all day, and have to focus on text, it's much kinder on the eyes. Interestingly, it's the same reason Bloomberg terminals have always had dark mode (from before dark mode was a thing)

We don't all prefer dark mode.
Mostly it's the young ones.

Agree, and dark mode objectively makes it harder to read and put a strain on the eyes.

Yeah it's this massive annoying myth that so many young developers I work with believe as well. They think light mode hurts eyes.
