I agree with her, I've been seeing the same problems with the physics community for decades. Everything kind of stopped after Einstein, and in particular I think nuclear weapons scared the heck out of everyone. I have long suspected that physics research since that time has been intentionally limited to "safe" areas like semiconductors, cosmology, and string theory. The old guard essentially decided that having physicists come up with death rays, superbombs, gravity warpers, and space travel was too risky. In the last several years the younger crowd of physicists have been re-examining some of the old physics and finding interesting gaps, so there may soon be much more progress. SpaceX may have found it relatively easy to be inventive in the space transportation arena because governments had final approval on any space projects for decades, leading to the stagnation of rocket development. I think there was a great desire to slow things down and keep technology from progressing faster than society could cope with it. You can argue whether that was good or bad.
