If we are truly trying to "replace human at work" as the definition of an AGI, then shouldn't the engineering goal be to componentize the human body? If we could component-by-component replace any organ with synthetic ones ( and this is already possible to some degree e.g. hearing aids, neuralinks, pacemakers, artificial hearts ) then not only could we build compute out in such a way but we could also pull humanity forward and transcend these fallible and imminently mortal structures we inhabit. Now, should we from a moral perspective is a completely different question, one I don't have an answer to.
