Every generation's test for machine intelligence is whatever machines cannot do yet, so in twenty years the question will be whether it can reproduce.

The problem is if you go back to 1960 and you tell them that you have a machine that can play amazing chess, of course someone in 1960 will tell you that machine is intelligent. Someone in 2010 won’t. What’s changed? Today, we think that these machines that have language are intelligent, but I think in 20 years we’re going to be like, yeah, but can it reproduce?
