But string theory is different because most of it is way outside the physical world which is accessible to experimentation. We can not probe beyond trhe 3 or 4 dimensions of our world. We can neither verify nor falsify the claims of that theory. And because of that I call it paper science. But maybe history proves me wrong and it is actually string theory that will show us how to build a warp drive...
Thanks for the explanation of your viewpoint. What I am saying is that I don't like, in general (not only because string theory), that plenty of people that are evidently not mad and put a lot of effort in their work are easily dismissed. This because the same can happen for all the fields that I think are non trivial.
I don't know enough about string theory to contest or confirm your view, but I would think that if enough smart people work on it, I trust them that it has some sort of meaning. Even if the string approach is completely wrong, maybe some byproduct of it will be useful.
As long as at least the theory stands (that is a way to refute hypotheses, although little for physics) we will have to wait.
Anyway I'd like to emphasize that the point of my comment is the dismissal of a subject without being expert enough in the subject itself.
The problem with string theory is that there are
two too many parameters whose values are unknown. By tweaking those parameters, the model can be made to fit anything, which makes it useless in terms of offering testable predictions about reality.

It may be elegant, but as it stands, it is not science.
