Re:Did the W-boson just “break the standard model”?

I'll simply have to disagree. The LQCD calculation of gA, for example, provides the tightest constraint on new right-handed currents beyond the Standard Model. The issue, of course, is that without a calculation the "new physics" is already incorporated into gA.

Make the computers 10x faster and the algorithms / libraries 10x faster and all the things you wish for are within reach. Much more plausible than _overthrowing the standard model with something that offers easier calculations_.
That means that such computations have little, if any, practical importance.
With the current QCD, it is not possible to compute the ratio between the mass of the neutron and the mass of a proton with a useful precision. The mass ratio between the proton and the electron or the mass ratios between light nuclei or their magnetic moments are even less possible to compute.
QCD would become a useful theory only when it would be possible to compute things like the probability of fusion of light nuclei with a precision good enough to eliminate the need to measure such values experimentally.
QCD would need revolutionary improvements to achieve such goals.
Supercomputers are not enough for a progress in this domain. Different solving methods must be discovered.
