My problem with him is the fact that he’s had firm control of Egyptian sites for far too long and that gives him firm control over the writing of Egyptian history
Lots of people are saying he is impeding if not totally preventing some of the newer non-destructive investigation technologies from being used.
Last I heard, they are actually pretty convinced now that there are some structures/tunnels under the paws of the Sphinx, just like Cayce said.
And in fact the whole Giza plateau is swiss-cheese riddled with tunnels and chambers.
