AI CPU implentation in minecraft

It would be awesome if Minecraft recorded everyones movements as a player in Minecraft servers or singleplayer. How the player walks, when, where to, what he does. So that out of this data CPU players can be created. There could be lots of great and fun implantations for the enjoyment of the player. For example, in minecraft servers when you play certain games that there could be AI CPU players mode so that there is no need for a minimal amount of real players in certain games for example bedwars, other games etc. But I also find it important that this mode could also be disabled so that you still have control if you want to play with real players or AI cpu players.
