I wouldn't take that "Stockfish paper" announcement at face value. As far as we could tell, Stockfish was used in a situation it is not optimized for (very many cores) and wrong settings. What we can say is that Alpha Zero is comparable after throwing a lot of specialised compute power at it. Most importantly, neither system works at a symbolic level or does anything even close to thinking. They handle statistics and see searches extremely well, sometimes tactics, but most of it is still hardcoded - they are fed a high level symbolic representation of the game. When Alpha Zero can learn playing chess by experimenting with board physics and observing a few videos or at least reading a book, then we can say it can actually produce some form of symbolic thought. (OpenAI is closer but nowhere near close - it falls back on memory of play as a full state model.)

There is ongoing open source, community based effort to replicate Alpha Zero Chess. The effort is lead by Gary Linscott. He is also one of the main developers of Stockfish (I believe the framework for testing Stockfish). https://github.com/LeelaChessZero/lczero https://github.com/LeelaChessZero/lczero Here is the current state of the effort: https://docs.google.com/spreadsheets/d/18UWR4FVhPi0vNwwPreu_avd9ycujGQ5ayR2LzJOWP4s/edit#gid=1045682900 https://docs.google.com/spreadsheets/d/18UWR4FVhPi0vNwwPreu_... Estimated date of surpassing Stockfish with settings and hardware reported in the spreadsheet is the end of this year. @edit I have missed your statements about symbolic reasoning. Yes, I'm referring to the same type of symbolic reasoning as the author of the article. I.e. system that manipulates high-level symbols without any grounded understanding of them in the surrounding us reality. Deliberating whether it is thinking or not is pointless. It's effective and that matters.
