The much more likely mass murder scenario: Deep Blue and other AI are programmed to most efficiently allocate resources for medical treatment. To save money, everyone over X age is shuffled over to hospice instead of saved, even though potential life expectancy and quality of life in later years continue to grow.
So based on cost savings criteria, you see millions of elderly and disabled denied care en masse.
Isn't that what happened with those Venezuelan voting machines in districts where obama won?
