Caledonian, this post also reminded me of that part of "The Planck Dive." But we should distinguish between the archetypal myths Sachio derides and human stories in general. I should think that Greg Egan's works still count as "human stories," even if they're not always about humans exactly. The characters are still lovable, comprehensible--I should say social. That there's physics doesn't eliminate the (trans)human element.
