8 Science-Fiction Predictions that Turned Out True (3 of 5)

Back to the Future II — Biometric Technology

Back to the Future II made a few wild predictions that will probably never happen, such as hovering skateboards or the Chicago Cubs winning the World Series…oh wait, they were only one year off with that one!
