Back when I was interested in theoretical physics (>15-20 years ago), String theory was the Hot Thing.
Imagine my surprise when, in a random browsing, I stumbled upon a science-themed blog "Not Even Wrong" written by Columbia University-associated Math professor Peter Woit where one of the comments by blog's owner stated (emphasis mine):
Many people thought the initial 1984 models for string theory unification were elegant, hardly anyone thinks that about the complicated mess you get out of a conjectural anthropic string theory multiverse.
“Enormous explanatory power” doesn’t really go with “can’t predict a single f—ing thing”….
Given that forming falsifiable predictions is the cornerstone of scientific method, the above quote sounded pretty damning to me.
QUESTION: Is it true that since 1980s, string theory - or at least parts of it associated with Anthropic principle have not made any (or any non-disproven) falsifiable predictions? Or was that comment somewhat hyperbolic?
