When Might AI Outsmart Us? It Depends Who You Ask

In 1960, Herbert Simon, who went on to win both the Nobel Prize for economics and the Turing Award for computer science, wrote in his book The New Science of Management Decision that "machines will be capable, within 20 years, of doing any work that a man can do." History is filled with exuberant technological predictions that have failed to materialize. Within the field of artificial intelligence, the brashest predictions have concerned the arrival of systems that can perform any task a human can, often referred to as artificial general intelligence, or AGI. So when Shane Legg, Google DeepMind's co-founder and chief AGI scientist, estimates that there's a 50% chance that AGI will be developed by 2028, it might be tempting to write him off as another AI pioneer who hasn't learnt the lessons of history. Still, AI is certainly progressing rapidly.
