When people make predictions about the advent of human-level AI, I wonder how many of them have a set of timed milestones in mind, and how many just express their feeling about when the now ends and a shimmering sci fi future begins.
That is only a shorthand for "human-level and beyond", i.e. a thing that can learn a Turing complete language and do universal function approximation. It will very likely scale, far above our level.
