Simulating a quantum system in a classical mechanical system may be possible in a limited sense, for trivial problems, but certainly not at speed. It's straight up P v NP. You will boil an ocean to watch any nontrivial simulation crawl frame by frame. But you wander off that point and return to the 'wet-and-noisy' argument he addresses explicitly in the abstract. Let's call it the Argument from Noise, or AfM. Again, if you read the abstract, you'll see K explains how this new discovery makes moot the AfM (but not rebut it, as a rebuttal or refutation requires an argument; making moot merely requires a contradicting observation. E.g. if the cops have a watertight argument for how, why when and where X murdered Y, it's moot if 100 reliable witnesses report X was playing acoustic folk-rock at a nearby cafe at the time.)
