The problem is that the bottleneck of the problem shifts away from the simulation and toward understanding. In other words, the scientists become the bottleneck because data takes time to fully understand. And once that understanding is achieved, there is still the issue of synthesizing chemical compounds that prevent misfolding, and that is assuming that such a thing even exists. Not all problems have a solution - but the potential benefits make it worth trying.
