This minifig of course would be able to talk, move, jump, learn, build, etc.
LOL YES THIS'D BE HILARIOUS TO SEE
Good luck fitting all the necessary parts for a robot into a tiny minifig.
All of the problems you stated are very easily overcome and a microscopic microphone and speaker would be easy to obtain. Joints can be added. The arms and legs can be covered in a rubber housing. Pistons in the legs would work fine too.
Congrats.Your ego made you turn a theoretical question into a "THIS CAN'T EXIST UR DUMB" argument.
