Does Artificial Intelligence Have A Dirty Little Secret?

After reading a recent pair of articles covering the topic of artificial intelligence (AI), I am confused. On one hand, there's recent PwC findings suggesting AI could drive $15.7 trillion in productivity gains by 2030. On the other, a recent piece from the New York Times makes a compelling case that, despite all the hype, AI's dirty little secret is that "it still has a long, long way to go." There's no question AI is a developing technology. As the New York Times piece points out, we can find plenty of examples of robots falling over while opening doors, driverless cars needing human intervention, and machines that still cannot read reliably at the level of a sixth grader.
