The current (July) SciAm interviews Leonard Susskind as a physics bad boy. Susskind praises Thomas Kuhn for paradigm shift theory, and gives Einstein's sudden discovery of relativity and spacetime geometry as his first example.
He is a big proponent of string theory, but he is down on reality because string theory will never say anything about reality. Now he likes the multiverse.
The Susskind interview is also criticized here. I also criticize him in my book. He was once a highly respected physicist.
