>Machines have surpassed humans by magnitudes in many capabilities already (how many billion multiplications can you do per second?)

Do you have any idea how many calculations it takes for a human to put a ball through a hoop while running across a court?

It could be millions or billions in a second. Manifesting consciousness, coordinating body movements, and everything else all at the same time takes calculations.

You may not be aware that your brain is doing multiplication, or any other kinds of math, constantly, but it is.
