I've been following computer go since MCTS was invented, and sorry. This is a funny delusion. The real reason Google is quitting now, is the same that IBM quit Deep Blue. Quit while you're ahead against other developers. Leela and Zen are already incorporating ideas from AlphaGo, and will be improving on them, like they improved on MCTS for close to ten years. Google can't afford to keep up, if they want AlphaGo to stay strongest. It's not a question of money, it's because they would have to keep top-notch machine learning experts working on it full time. But humans? Humans will start losing to all strong programs, not just AlphaGo. These programs don't have any obvious exploitable weaknesses, you know. Even pre-neural net Zen and CrazyStone were 6-7 dan on KGS - for perspective, many very smart people who play Go competitively will never reach that level. It's top club player level. Most European countries don't have a single player on that level. And the current neural net bots besides AlphaGo are even better - pro level. 9d on KGS (the max).
