Computers are dumb to begin with. They do exactly what we tell them to do. If I want a chess engine to not pick the optimal move every turn, I just tell it not to. A chess engine will think of several possible moves and rank them from best to worse. I can program it to pick only its third best option for instance to make an easier opponent.

Imperial is easy to eyeball and is in human sized chunks of understanding. Metric is precise and easy to do math with.

Imperial measurements were based on physical objects that were commonly available to people at the time. Which made measuring imprecise but practical for people.

Metric was developed to use as few physical objects as possible to precisely define any unit of measure. These days they are defined by fundamental aspects of the universe so anyone can come up with the same measurements.

Imperial as it stands today is now defined by metric measurements because we need to be precise.
