Having a high enough accuracy will give you a "good idea" of the interactions it might have with other proteins and substances, but can't account for the millions of other interactions they might have with other particles.
Most of the bioinformatics aren't deterministic, but still rely on stochastic measures. DNA sequencing is done by sampling, then predicting the rest and as far as my own biology teachings go, it's categorized as "solved". Sequencing might get better, but we've accepted it as a solution for the moment.
Arguing the term "solved" is just pedantic. We know it's not 100%, but the actual usefulness of improving the prediction of a few more Angstroms isn't going to make a huge practical difference.
What matter is that we can start actually building tooling and lab tests on this method.
