After beating the worlds elite Go players, Googles AlphaGo AI is retiring

Googles AlphaGo the AI developed to tackle the worlds most demanding strategy game is stepping downfrom competitive matches after defeating the worlds best talent. The latest to succumb isGostop-ranked player,Ke Jie, who lost 3-0 in a series hosted in China this week.

The AI, developedby London-based DeepMind, which wasacquired by Google for around $500 million in 2014,also overcomea team of five top playersduring a week of matches. AlphaGofirst drew headlines last year when it beatformer Go world champion Lee Sedol, and theChina event took things to the next level with matches against19-year-old Jie, and doubles with and against other top Go pros.

Challengers defeated,AlphaGohas cast its last competitive stone, DeepMind CEO Demis Hassabis explained.

This weeks series of thrilling games with the worlds best players, in the country where Go originated, has been the highest possible pinnacle for AlphaGo as a competitive program. For that reason, the Future of Go Summit is our final match event with AlphaGo.

The research team behind AlphaGo will now throw their energy into the next set of grand challenges, developing advanced general algorithms that could one day help scientists as they tackle some of our most complex problems, such as finding new cures for diseases, dramatically reducing energy consumption, or inventing revolutionary new materials.

Go is revered as the planets most demanding strategy game, and thats why it made for an ideal field to both develop AI technology and plot machines against humans. Beyond Google, Tencent is among other tech firmsto have unleashed AIs on the game. While it whips up curiosity and attention,the game simple servesas a stepping stone for future plans which is why DeepMind says it is moving on.

Indeed, the British companyhas already made a foray into more practical everyday solutions. Last year, it agreed to a data-sharing partnership with the UKs National Health Service, however the partnership has been criticized for givinga for-profit company access topersonally identifiable health data of around1.6 million NHS patients.The original arrangement remainsunder investigation by the UKs data protection watchdog, the ICO.

Those snafus arent a reflection on the technology itself, however, andHassabis remains bullishon the impact his firm can make.

If AI systems prove they are able to unearth significant new knowledge and strategies in these domains too, the breakthroughs could be truly remarkable. We cant wait to see what comes next, he said.

While AlphaGo is bowing out at the top, it isnt done with Go altogether. DeepMind is planning to publish a final review paper on how the AI developed since its matches with Lee Sedol last year. It is also developinga teaching tool to help newcomers pick up the ropes of the highlycomplicated game, and to enable more experienced handsto learnthe new and innovative moves that Go has introduced. Top players, even Ke Jie himself, studied up on AlphaGos moves andadded someto their arsenal.
