It shouldn't be an AI made specifically for chess. Think of a general ai for a task other than chess - like gpt for language, or sora, or Dall e.
Clarifications:
Does it actually have to play a game or can we derive this being true from its ELO score against say Stockfish?
I assume this is considered "true" already for Deepmind due to MuZero?
@Uaaar33 I agree. This should already resolve YES because of MuZero. It wasnt created specifically for chess and it is A LOT more general than just a "chess engine". Also I am guessing at least one super grandmaster lost at least once against it (maybe not, idk).
AIs in 2028 will probably be optimized for planning and accomplishing common economically useful real-world tasks, but beating a super grandmaster at chess is pretty specialized. I would guess that even a very smart human - say, Leonardo da Vinci or Terence Tao - would probably have to work quite hard to attain that level of chess-playing, so I doubt that an AI could do it without at least some specialized fine-tuning.
Also, I'm not sure that a super grandmaster would try playing one of these generalized AIs by 2028, even if it had the capability to beat them.
