I agree 100% that most mathematicians prefer proofs presented in a clear and
understandable way, and having taking classes from Gromov I think he is good at
that.
I would be, however, very careful as classifying this phenomenon as "rigor
giving way". This phrase seems to imply, to me, a meaning that Gromov does not
actually prove his results (in the normal mathematical sense of this word),
just presents some intuitive arguments for them. This is absolutely not true.
He HAS proofs - as judged by the math community and by the referees of his
numerous papers, but he does not present them in all gory detail in his
lectures and his papers.
I am not sure if Matt had this meaning in mind or not, I just wanted to
emphasize that this phrase may be interpreted this way.
