I once had a physics professor (who I admittedly was not too close to) who loved mathematica and is quite the evangelist for the tool at my old school. However, he once met Stephen Wolfram and didn't feel that he had "a high opinion" of my professor.

Regardless of his ego, he has somewhat earned the bragging rights given that he is responsible for mathematica and wolfram-alpha.

Ugh and he just had to say "it's a new kind of thing". No, it's not new. It's a very sophisticated implementation of some very old ideas. Surely that's impressive enough. Why wouldn't you cite the prior art??
