The Benefits of Thinking Hard About String Theory
I think that we've gotten some benefit from thinking so hard about string theory. On the other hand, I do think that it has had an effect on the physics community which is not entirely salutory. The one possible counter example there is holography itself. Holography can be thought of as spread out over the horizon of the black hole rather than scattered through the interior. So something non-local and lower dimensional. In arguably, the first person to put forward that idea was Gerard Atuf. He did it before Susskind did, but Suss Kind did in a way that was much clearer to the rest of the community and much more dramatic.
