This speaker reminds me of my childhood in Budapest. There were gypsy magicians who came to town to entertain us children. But as I recollect, there was one important difference: the gypsy only seemed to violate the laws of nature, he never really violated them!
I came to realize that exaggerated concern about what others are doing can be foolish. It can paralyze effort, and stifle a good idea. One finds that in the history of science, almost every problem has been worked out by someone else. This should not discourage anyone from pursuing his own path.
