# Difference Engines
[[Marvin Minsky]] argue in [[Society of Minds]] the concept of **difference engines**, I find it quite similar to [[Supervised Learning]], agents are given a goal and they tinker by trial and error while improving toward having less difference with the expected result.
Well, supervised learning doesn't scale so it's **BAD**, we can't rely indefinitely on human feedback.
