The Surprising Path Of Artificial Intelligence

Vinod KhoslaArtificial intelligence touches our lives in the form of chess computers that are better than most humans, computers beating the best humans at Jeopardy, intelligent ad targeting, Microsoft Kinect recognizing human motion and even amazingly, Googles self-driving car that drove itself from San Francisco to Los Angeles. Intelligent systems can even do transactions involving judgment like investing on Wall Street (a former MIT mathematician is now a hero on Wall Street with one of the best performing investment funds for many years in this judgment-based domain) and of course Siris conversational interface that does what you ask (mostlythink of Gen 1.0 as a high-IQ three-year old getting better with each passing year). Computer Jeopardy champions, self-driving cars and Siri-like conversational interfaces would have seemed very hard a few years ago.Rather than the brute force logic-based development that was envisioned with Commander Data, successful systems have been built from examples rather than logical rules. We essentially let the computer figure it out using lots of past problems and solutions that include probability assessment systems beyond any hard-coded rules. Reasoning under uncertain conditions underlies a major area of recent progress.
