> What even is "system one"

I definitely agree it's underexplained in type safe.ai's materials.

I have to assume it's a reference to the fast, heuristic, intuitive "system 1" process in humans, as opposed to the slow, procedural, reasoning "system 2".

This theory is recognized, among others, in Daniel Kahneman 2002 Nobel prize on Economics.
