Walk into your kitchen right now. You'll reach for the light switch without thinking. You won't check whether the floor is still solid, whether gravity still works, or whether the walls have changed colour since yesterday.
You know these things haven't changed—but you don't know them the way a mathematician knows that 2 + 2 = 4. You know them because you simply don't consider them. You filter out the 99.9% of reality that is irrelevant to the task at hand.
This effortless filtering is something you do thousands of times a day. It is so natural that you have never once thought about it.
A machine cannot do this.
