I would say that for all practical purposes chess has been "solved" in the sense that I don't believe even the World Chess Champion would win one game out of a hundred against them today.
That's a strong claim; I wonder what the numbers are. Nevertheless, the top chess engines are now 500 FIDE points better than the top grandmasters. At that level of play, 500 point upsets are incredibly rare. It is possible for a 2300-level player to beat a 2800-level player, but even though that happens once in a (very long) while no one insists that the 2300 level player is comparable to the 2800 level player. I'm confident that computers are now better than humans for the same reason.
