I actually like Eric Weinstein. He does have a bit of a persecution complex, is overly proud of his half-baked contributions, and has a narrowed worldview brought on by his humble superiority complex, but he is actually very smart and tends to see through a lot of BS. The fact that he would then like to sell you his own BS is beside the point. He is usually very upfront about the limits of his own understanding.

I wish I knew physics better so I could evaluate Geometric Unity, I may be completely hoodwinked because I am simply not as intelligent as he is, but I suspect that even if his solutions are wrong, his approach is probably correct. By that I mean making the assumption that our physical constants are a consequence of the mathematics and not a fine-tuning. (I might be saying that wrong as well)
