He's hubristic and selfish. None of his "research" is going to benefit anyone (himself included), making this essentially a huge waste of time and resources. Bryan will die just like all the rest of us, despite being very rich and self-obsessed. He could spend his enormous wealth on supporting real research and proper studies on real diseases that hurt lots of people. Instead he's acting like just another huckster promising a fountain of youth. He does this using bombastic terms and taboo methods (e.g. using his son as a blood boy), in a way that's calculated to direct enormous public attention towards himself. The science he advocates for is sketchy at best and the results of all his "experiments" will tell us nothing because we can't reproduce his methods (his program allegedly costs >$1M per year), nothing is blinded or controlled, and N=1. He's a bad person who uses bad methods to glorify himself and now he probably gave himself an autoimmune disease. He deserves to be mocked.
