@sfleetucker He didn't come up with that himself. It's part of a hypothesis put forth in the 1980s by Peter Duesberg, an otherwise respectable professor at UC Berkeley; the other part is collapse of the immune system by malnutrition and/or exposure to multiple microbes. It was a reasonable hypothesis in the late 1970s/early 1980s, when we knew little about AIDS epidemiology and nothing about HIV.
Despite evidence, Duesberg never retracted it, leading to deaths in South Africa and elsewhere.
