Exactly. I am becoming increasingly convinced that this is actually just a part of how intelligence/cognition works.

But is it really what we want, machines with the same defects as humans? I don't want a pocket calculator that make mistakes "sometimes" so I have to double-check the results, I want a pocket calculator that works (to those who want to argue that pocket calculators don't give the correct result for (1/3)*3: STFU).
