This line of argument feels like it has an implicit assumption that progress for ai technology is to become more human-like. This is certainly a requirement if the objective is to replace humans, but ai could grow to be increasingly more sophisticated, capable of doing more and more tasks by progressing on different paths. This is not to say that the singularity is imminent, but the argument "Human intelligence has X as a necessary piece, AI has little amount of X so it is not intelligent" does not sound convincing to me.
