Some knowledge is encoded in them, somehow. Just like knowledge is encoded in our brains somewhere (mb NN structure, mb RNA, mb combinations of that and other things). It’s also like how knowledge is encoded in genes, or printed words, or the states of electrons in a computers memory. Maybe a better way to say it would be like a shadow or projection of some knowledge is encoded in those things. But we don’t know how to read or understand those encodings generally. (It’d be a big deal if we did)
Yes, it’s up to you and/or @doubtingthomas. It depends on your goals. I think Elliot’s comments in Friendly Category Posting Policies Question give some good background on the Friendly category and what’s okay/not okay. In this case, reducing complexity was just my suggestion, but I’m not going to be pushy about it or criticize you for talking about AlphaZero or things. (Well, I’m going to try to be like that, and it’s fair for someone to call me out if I’m not being like that)
