University of Missouri assistant professor SCOTT CHRISTIANSON puts an app designed to assist those with visual impairments to the test using yours truly, our floor director and some wrinkled up dollar bills. Self-driving cars is becoming a reality, and while it may sound like a cool idea, PROF. SCOTT CHRISTIANSON points out a not-so-obvious morality dilemma when it comes to programming machines that are designed to make decisions that a human normally would, saying "hopefully the car will be able to avoid the accident, but there may be situations where it may not be able to, so how do we want those cars programmed?" Never mind tomorrow, machine-learning artificial intelligence is happening now! University of Missouri professor SCOTT CHRISTIANSON tells us just how much it's "creeping into our lives."
