How Real is Artificial Intelligence?

All of a sudden, AI is everywhere--in consumer products, in our entertainment, in our consciousness. Every day we hear stories from Google, Uber, Baidu, Microsoft, Amazon and others about unprecedented achievements in language translation, gaming, image recognition, music composition, beer-delivering driverless trucks, and a host of achievements, all powered by AI. But what is AI, really? And, to be fair, do we even understand what intelligence is? In 1983, and long before what we think of now as the Internet, a developmental psychologist named Howard Gardner published what is now a seminal work on the "Theory of Multiple Intelligences".
