So far string theory is still the Science Fiction of complex mathematics because all the experiments expected to see it have found nada.If you believe what most scientists believe, then you believe that life in the universe is not limited to our own planet.
More to the point, if you believe in super string theory then you believe in pure energy, but if you dont believe in SST then maybe you dont believe in pure energy.
It's wrong to totally dismiss this though because although it is not proven, it is still not science fiction.
Science fiction is something totally made up without necessarily any grounds to show that it is real. That's not what science does. The Higgs boson is a good example of how this process works. If the shoe fits, wear it

Horgan: You've recently denounced “fake physics.” What is it? Are journalists mostly to blame for it?
Woit: By "fake physics" I mean pseudo-scientific claims about physics that share some of the characteristics of "fake news", in particular misleading, overhyped stories about fundamental physics promoting empty or unsuccessful theoretical ideas, with a clickbait headline. Those most to blame for this are the physicists involved, who should know better and be aware that the way they are promoting their work is going to mislead people. Journalists need to be skeptical about what they're being told by scientists, but often they're more or less accurately reporting impressive sounding claims being made by physicists with impeccable credentials, and not in a good position to evaluate these.
Horgan: Do you still think string theory is “not even wrong”?
Woit: Yes. My book on the subject was written in 2003-4 and I think that its point of view about string theory has been vindicated by what has happened since then. Experimental results from the Large Hadron Collider show no evidence of the extra dimensions or supersymmetry that string theorists had argued for as "predictions" of string theory. The internal problems of the theory are even more serious after another decade of research. These include the complexity, ugliness and lack of explanatory power of models designed to connect string theory with known phenomena, as well as the continuing failure to come up with a consistent formulation of the theory.
