The real danger is the uncritical eagerness with which such engines are being placed in control of serious real-world issues. An AI doctor, for example, programmed to dispense proper treatment only to proper people. An AI traffic director that knows the race and political persuasion of its powerless customers and adjusts accordingly. An AI producing differential pricing at restaurants and grocery stores adjusted for social scores, to which the customer cannot deny access because the only permissible means of payment links to that data. These are essentially babies presented with loaded guns - the damage will be done before they know any better.
Here's it's idea of a Viking:
"Finally, the Rock has come back..."
"...to England."
Dwayne Johnson should put that on a wall.
