"There’s a scary lesson in these contests between the grandmaster and his soulless opponents. We are sharing our world with another species, one that gets smarter and more independent every year.

Could we ever face anything akin to the horrendous sci-fi nightmares that we see in “Terminator 3”? In the long run, it’s well worth worrying about. But the machines aren’t worried at all."
