It’s everywhere. On our phones. In our rooms. It’s even in the vehicles we drive.
The error may be big. The errors may be small. But they are there.
After all, humans built everything we see.
Even in the most extreme situations (space launches, weapons, etc.) human error is a component.
All humans have their flaws. We all inevitably make mistakes.
So whenever you encounter a problem and think “this doesn’t make sense”.
Realize that maybe, JUST maybe, the person who designed it wasn’t infallible.
Maybe YOU could have done it better.
It may just give a different perspective.
