Doesn't Arthur Clarke's quote, "Any sufficiently advanced technology is indistinguishable from magic," that I believe you used in another post, imply that the type of "computer" needed to simulate the universe is completely possible?
The point of my article is that the universe isn't unfolding the way a computer calculation unfolds because it is quantum, and multiply connected. Another way of saying it: The universe is a quantum computer 20 billion light years across.
It makes sense that the universe would be the most efficient system for "calculating" itself as nature tends not to be wasteful. I would only mention the existence of analog computing. It doesn't change the conclusion of your analysis-- analog computing can provide, at best, several orders of magnitude of increased computational performance, not enough to grow exponentially with the number of particles being simulated, but enough to suggest that digital-quantum hybrid computing will (or maybe already is) occupying a niche analogous to digital-analog hybrids in the 1950's and 60's. Perhaps digital-quantum hybrid computers could more easily solve some of the multi-particle quantum interactions hinted at by the DNA and photosynthesis processes you've mentioned.
We think of the world as an analog computer at large scales, but the whole idea of a quantum is the essence of digitalness. Of course, no one knows what physics is like at the Planck scale, but physicists seem confident that on the Planck scale, even space and time are pixelated.

Lol ya I knew that I was just testing you ;)

Iow the universe is magic
