The article seems to assume that there will be one researcher or research organization producing one AI. This makes it reasonable to propose asking it a super-special question that reduces the risk. It's more likely that armies of researchers will be competing to create quantities of ever-smarter AI's: for trading stocks, diagnosing illness, or managing enterprises.
