[...] In my view this is exactly the sort of thing that demonstrates why its wrong to dismiss string theory as "non-predictive". This attitude simply fails to grasp that string theory is not analogous to the standard model, but to quantum field theory. People still have to write down a model in order to make a prediction, just like always. Now that process just has taken on a totally different set of constraints, that in many ways are far more restrictive than before. Scientifically the only difference is that now we call it "choosing a vacuum", but its scientifically the exact same thing as "postulating a Lagrangian" in quantum field theory, like the one that earned Higgs and Énglert the Nobel Prize.
