I would agree that the computational complexity of every single quark in every single atomic particle in every atom in every synapse is far far greater than the computational power we poses at this day. I just think it's a red herring to chase down that level of computational completixy (for now. True physical simulations truly amaze me, and I can't wait to see them be more granular and accurate). When it comes to intelligence, I think we are mostly missing the algorithm, not the computational power. I think once somebody finds the algorithm (which may be very soon in my own opinion), we will have more than enough computational power to blow the mind away by orders of magnitude.
