Chess is a closed system w/ finitely many rules. I don't think success in closed domains transfers to open ones & this is the usual error optimists are making about AI & its success in closed domains like chess. Continuous learning is necessary for open domains b/c real world distributions are constantly changing & unless deployed systems can keep up w/ the changes their performance will continuously degrade until they're worse than random. Chess has been the same for millenia & that's why chess is essentially solved.
