Kasparov: Self-driving won't be perfect

When chess grandmaster Garry Kasparov considers self-driving cars, he thinks of elevators: for the first half century they were in use, almost no one would get on one unless an operator was aboard to push the buttons. But then, in 1945, elevator operators went on strike.

Why it matters: With a soothing ad campaign, the industry got people to stop sweating, and push their own buttons. So it is with autonomous driving, Kasparov told the WSJ Future of Everything Festival yesterday in New York: "No machine will reach 100% perfection, but it will be much safer."
