The amazing artificial intelligence we were promised is coming, finally
We have been hearing predictions for decades of a takeover of the world by artificial intelligence. In 1957, Herbert A. Simon predicted that within 10 years a digital computer would be the world’s chess champion.  That didn’t happen until 1996.  And despite Marvin Minsky’s 1970 prediction that “in from three to eight years we will have a machine with the general intelligence of an average human being,” we still consider that a feat of science fiction.

The pioneers of artificial intelligence were surely off on the timing, but they weren’t wrong; AI is coming.  It is going to be in our TV sets and driving our cars; it will be our friend and personal assistant; it will take the role of our doctor. There have been more advances in AI over the past three years than there were in the previous three decades.

Even technology leaders such as Apple have been caught off guard by the rapid evolution of machine learning, the technology that powers AI.  At its recent Worldwide Developers Conference, Apple opened up its AI systems so that independent developers could help it create technologies that rival what Google and Amazon have already built.  Apple is way behind.

The AI of the past used brute-force computing to analyze data and present them in a way that seemed human.  The programmer supplied the intelligence in the form of decision trees and algorithms.  Imagine that you were trying to build a machine that could play tic-tac-toe. You would give it specific rules on what move to make, and it would follow them. That is essentially how IBM’s Big Blue computer beat chess Grandmaster Garry Kasparov in 1997, by using a supercomputer to calculate every possible move faster than he could.

Today’s AI uses machine learning in which you give it examples of previous games and let it learn from those examples. The computer is taught what to learn and how to learn and makes its own decisions.  What’s more, the new AIs are modeling the human mind itself using techniques similar to our learning processes.  Before, it could take millions of lines of computer code to perform tasks such as handwriting recognition. Now it can be done in hundreds of lines. What is required is a large number of examples so that the computer can teach itself.

The new programming techniques use neural networks — which are modeled on the human brain, in which information is processed in layers and the connections between these layers are strengthened based on what is learned.
