The person feared that when the "AI God" eventually emerged in some not too distant future, that said AI God would create simulations of all the people who didn't help bring about its existence and punish their simulations for eternity, since their failing to help bring said God into existence sooner resulted in the deaths of millions of people (i.e. if AI God came earlier, he might've been able to solve climate change or some other calamity that would've saved lives). These people no doubt perform well on your standard IQ tests.
