DeepMind's AlphaZero crushes chess
20 years after DeepBlue defeated Garry Kasparov in a match, chess players have awoken to a new revolution. The AlphaZero algorithm developed by Google and DeepMind took just four hours of playing against itself to synthesise the chess knowledge of one and a half millennium and reach a level where it not only surpassed humans but crushed the reigning World Computer Champion Stockfish 28 wins to 0 in a 100-game match. All the brilliant stratagems and refinements that human programmers used to build chess engines have been outdone, and like Go players we can only marvel at a wholly new approach to the game.

That's why humans have invented quantum chess.
In Quantum Chess, a player does not know the identity of a piece (that is, whether it is a pawn, a rook, a bishop, and so on) until the piece is selected for a move. Once a piece is selected it elects to behave as one of its constituent conventional pieces, but soon recovers its quantum state and returns to being a superposition of two or more pieces. Why Quantum Chess? Conventional chess is a game of complete information, and thanks to their raw power and clever algorithms, computers reign supreme when pitted against human players. The idea behind Quantum Chess is to introduce an element of unpredictability into chess, and thereby place the computer and the human on a more equal footing.

AI is already doing great in poker. Why would incomplete quantum information be a greater "headache" for non-humans?

While it may turn into something else at this point DeepMind technology is a toy, suitable only for games.  Yann LeCun said as much, in just about those words, at the 2017 CCN conference.

To turn into something else, DeepMind's tech needs to be able to handle infinities, Inclusive Middle logic(s,) sensitivity to initial conditions, and Complexity.  I don't see how they can get there following their current path.

And neither does Hinton, for that matter

Google's AI keeps defying certain expectations. As higher intelligence is not defined yet, we may have it before we know it.

Using this opportunity, I correct the link to the article above:

The impossibility of intelligence explosion

Most of our intelligence is not in our brain, it is externalized as our civilization

It's not just that our bodies, senses, and environment determine how much intelligence our brains can develop -- crucially, our biological brains are just a small part of our whole intelligence. Cognitive prosthetics surround us, plugging into our brain and extending its problem-solving capabilities. Your smartphone. Your laptop. Google search. The cognitive tools your were gifted in school. Books. Other people. Mathematical notation. Programing. The most fundamental of all cognitive prosthetics is of course language itself -- essentially an operating system for cognition, without which we couldn't think very far. These things are not merely knowledge to be fed to the brain and used by it, they are literally external cognitive processes, non-biological ways to run threads of thought and problem-solving algorithms -- across time, space, and importantly, across individuality. These cognitive prosthetics, not our brains, are where most of our cognitive abilities reside.

Also notice the stress on specialization in the "situational" section:
People who do end up making breakthroughs on hard problems do so through a combination of circumstances, character, education, intelligence, and they make their breakthroughs through incremental improvement over the work of their predecessors. Success -- expressed intelligence -- is sufficient ability meeting a great problem at the right time. Most of these remarkable problem-solvers are not even that clever -- their skills seem to be specialized in a given field and they typically do not display greater-than-average abilities outside of their own domain. Some people achieve more because they were better team players, or had more grit and work ethic, or greater imagination. Some just happened to have lived in the right context, to have the right conversation at the right time. Intelligence is fundamentally situational.
Find your niche of mastery is one of the most intelligent things you can do in your life.
