(Substitute the word SMART for RICH, is my suggestion)
Still, it's easy to see why this line of thinking appeals to the Silicon Valley Super-Rich: 'cos if Nothing is Real (Cue: John Lennon's voice) -- that this is just some sort of quantum-code simulation of Reality -- then it absolves you of any social responsibility in the Now.
Still this fella thinks there's some serious mileage in the idea:
"Observable consequences of the hypothesis that the observed universe is a numerical simulation performed on a cubic space-time lattice or grid are explored. The simulation scenario is first motivated by extrapolating current trends in computational resource requirements for lattice QCD into the future. Using the historical development of lattice gauge theory technology as a guide, we assume that our universe is an early numerical simulation with unimproved Wilson fermion discretization and investigate potentially-observable consequences. Among the observables that are considered are the muon g-2 and the current differences between determinations of alpha, but the most stringent bound on the inverse lattice spacing of the universe, b^(-1) >~ 10^(11) GeV, is derived from the high-energy cut off of the cosmic ray spectrum. The numerical simulation scenario could reveal itself in the distributions of the highest energy cosmic rays exhibiting a degree of rotational symmetry breaking that reflects the structure of the underlying lattice."
The Matrix has got a lot to answer for.
