Your brain is a slab of wet meat, not a logic engine. It can't find actual flaws in your code - it's just half-decent at pattern recognition.

That is not exactly true. The brain does a lot of things that are not "pattern recognition".

Simpler, more mundane (not exactly, still incredibly complicated) stuff like homeostasis or motor control, for example.

Additionally, our ability to plan ahead and simulate future scenarios often relies on mechanisms such as memory consolidation, which are not part of the whole pattern recognition thing.

The brain is a complex, layered, multi-purpose structure that does a lot of things.

Its pattern recognition all the way down.
