Why would fusion power result in "enourmous abundance" of usable energy? A fusion power plant would not run on magic, it is an extremely complex, very expensive high-tech system which requires human oversight, maintainance, and fuel.

Yep - our already built fission plants are starting to go out of business because the power they produce is too expensive. I don't think we should bank on fusion plants being incredibly inexpensive to operate.

Well, yeah, I wasn't too convinced myself.

Perhaps self-replicating solar array in space level of abundance?
