One day when I'm not being lazy I might publish a point by point refutation of the usual nonsense anti-string theory memes. Until then, here's what I said on this point 25 days ago, specifically the first paragraph starting with "like another commenter".
OK, but if there are no predictions that we can test for several generations, how do you tell the difference between science and science-sounding nonsense?
In other words as we probe lower scales, string theory predicts thtat Lorenz invariance will never break,
as long we have to do with a consistent string like theory.
Is my understanding correct?
