I think that the whole gamut of "string theories" are not much more than mental masturbation for some high end mathematicians who feel that paradigm breaking should become the norm.
They have zero physical support, they are based on very weak, esoteric math, and they are becoming, almost daily, more and more complex. This all flies in the face of any other "great theory".
They're putting all this time and talk into making a hideously complex solution for particle physics, when the Standard Model is 95% there already...and most of what is not verified yet is in the ultra-high energy regime, which we should break into in the next 20 years at most.
Why create tie-dyed science when the nuts and bolts of the Standard Model work just fine, AND accurately predict things?
Now, if the String people would just admit that they're playing with math, and creating thought experiments, and not trying to solve the Universe...then I'd be OK with that...but don't go calling String the next Theory of Everything...
but...again...that's just my opinion
