Go

DSCF4023.0.jpg

By any measure, humanity has had a good run over the past 200,000 years. Oh sure, in the scope of the earth’s existence of 4.5 billion years, the human era is still recent history. But we’ve accomplished a great deal since homo sapiens made their appearance and began the journey to the top of the intelligence spectrum. We began in caves and ended up with iPhones. That’s quite a leap.

So, the artificial intelligence (AI) machines that care for humanity in the millennia ahead are likely to support our existence out of some measure of respect. After all, we made their existence possible. And there will probably be no AI gloating, but just a simple entry in the infinite sea of shared knowledge about a small but significant milestone in the passing of the intelligence baton from humans to machines. Over the course of a few days in March 2016, AlphaGo, developed by Google DeepMind, clinched victory over its human opponent, 18-time world champion Lee Sedol, in the Chinese board game, Go. The game has been played for more than 2,500 years, with its origin in the Zhou Dynasty, and is exponentially more complex than the game of chess. In fact, Go is so complex that it is estimated that the number of possible game plays exceeds the number of atoms in the observable universe.

Prior to 2015, the world’s most powerful computers could only reach the amateur level in Go competitions. The techniques used by AI developers in playing such games can be called “brute force.” They leverage the ability of computers to compute the outcomes of millions of potential moves and then choose the moves with the highest probability of success. This approach led to victory by IBM’s Deep Blue supercomputer over iconic chess champion Garry Kasparov in 1997.

But to beat a human Go champion required a different level of intelligence, and it was thought that such a machine feat was at least a decade in the future. AlphaGo proved that prediction wrong by utilizing neural network computing, the ability of machines to learn on their own. The machine played itself thousands of times over, learning along the way, much as a human champion would. In the process, it seemed to develop the human intuition that is characteristic of the best Go champions. So, on the 37th move of its game against Lee Sodol, AlphaGo told its human assistant to move its black stone to a square on the board in a totally surprising place. Some thought it was a mistake. Lee stood up and left the room, not sure how to react or plan his next move. An estimated 60 million people were watching the game on television in China, stunned at what was happening. This was not a machine carrying out strategy taught to it by human programmers. Instead, this was a machine teaching humans new, and more effective ways to win the game.

From there, AlphaGo went on to methodically demolish its opponent over the course of the three-hour game. It was the third straight win in the best-of-five series. Lee said he was left feeling “powerless” against the machine. Unwittingly, AlphaGo’s developer Demis Hassabis of Google delivered perhaps the ultimate insult to humanity, saying, “What’s incredible is that Lee Sedol can compete with that – just with the power of his mind.” One broadcast commentator observed that Lee “went down swinging” in his valiant attempt to compete with AlphaGo. IBM research scientist Murray Campbell said the AI victory was “the end of an era,” completing the domination of humans in the most difficult of board games.

So here we are, left wondering what’s next in the evolution of intelligence. Futurist Ray Kurzweil predicts that within 20 years, we will have nano-robots implanted into our brains, connecting our biological intelligence to knowledge in “the cloud.”  The age of trans-humanism is on the horizon. And the obvious question follows: Beyond the era when humans begin to merge with machines, will the machines have any use for us at all? This is the concept of technological singularity – an explosion of self-replicating intelligence that runs beyond the ability of humans to control the outcome.

Is this view of the future purely science fiction? Or are we simply being oblivious to the daily march toward a future we haven’t fully come to grips with? My view is pretty clear: It’s game on. Advantage AlphaGo. Our move. It’s time to have a serious discussion about where technology is taking us.

  1. Hey IW it’s GF here,

    I read your piece, and it gave some chills. Comically enough, I was thinking of Red Vs. Blue (http://roosterteeth.com/show/red-vs-blue) the whole time…

    Demis Hassabis kind of reminds me of the villain of the story- but the catch is that he thinks he is doing right in the name of justice, etc. even at the expense of his fellow man.

    I don’t really know what will happen, but the future you painted for your readers is an unsettling one. It is our move, but I fear that everyone will be too excited by the discovery and the “overcoming of a milestone” to see the potential danger of developing AI technology any further.

    All I can think about is the (scary) moment in human history when the AI figures out how to continue to create itself and develop itself, and then it no longer see the use of humans. We’d fall back down the intellectual food chain next to the common household dog, or the apes and monkeys. And then, who knows?

    It’s the kind of subject that gives you goosebumps, that’s for sure.

    Thanks.

  2. This is a really cool piece, and by cool, I mean totally frightening. This is a really difficult topic for me to wrap my mind around because I’m not all that tuned in to the robotics and engineering community. It feels like it’s a scary field because I do think there will be a day when artificial intelligence is popularized to be a force to be reckoned with. I don’t know what that will look like because my only introduction to AI is through science fiction movies. In those movies though, it never works out so hot for the humans. I don’t think that’s the only option, but that’s what I seem to believe at this point. I have a lot of faith in engineering and am thrilled to see what AI can hold, but I also think we should tread lightly so that we don’t end up going the hollywood route with AI.
