And how would you measure Intuition then? Maybe she had terrible intuition but is just a fantastically productive programmer.

Correlation not implying causation is a big deal because it's possible to draw (probably exponentially) many alternative causal chains than the one that you're discovering correlation along.

If the above isn't the case, and it's at least theoretically possible to design experiments like that, then correlation does[1] equal causation.
