In an earlier blog article I wrote about how human intelligence differs from artificial intelligence, namely human intelligence is general intelligence while artificial intelligence is specialized intelligence. The article provides "food for thought" for those who fear technology evolution, and specifically AI. In today's article I offer more reflections on the evolution of AI. Put in simple words, AI is about Thinking Machines. The English computer scientist Alan Turing was the first academic who proposed to consider the question "Can machines think?" in 1950.
Here are the slides from my York Festival of Ideas keynote yesterday, which introduced the festival focus day Artificial Intelligence: Promises and Perils. I start the keynote with Alan Turing's famous question: Can a Machine Think? and explain that thinking is not just the conscious reflection of Rodin's Thinker but also the largely unconscious thinking required to make a pot of tea. I note that at the dawn of AI 60 years ago we believed the former kind of thinking would be really difficult to emulate artificially and the latter easy. In fact it has turned out to be the other way round: we've had computers that can expertly play chess for 20 years, but we can't yet build a robot that could go into your kitchen and make you a cup of tea. In slides 5 and 6 I suggest that we all assume a cat is smarter than a crocodile, which is smarter than a cockroach, on a linear scale of intelligence from not very intelligent to human intelligence.
If you happen to have a free 30 hours or so, I would highly recommend watching Google's AlphaGo program take on one of the best players in the world at the ancient Chinese board game Go. If you don't have that much time, you could instead just watch the 6-hour third match, where the program wrapped up the best of five series. It's literally history being made. Some news outlets have covered this feat, but I don't think many people understand how monumental this actually is. Back in 1997, when Garry Kasparov was beaten by IBM's Deep Blue in chess, people were more excited about the future of computing.
