There is an apocalyptic scenario in which Bitcoin eats the world. In this scenario, a bitcoin becomes so valuable that no other activity is worth more than mining bitcoins, and all the power and resources in the world are devoted solely to Bitcoin mining.

I won't go further this line of your post since in any apocalyptic scenario as, world wouldn't gather power just to dedicate it to mine bitcoin. What would be the purpose?
Besides transacting bitcoin isn't helpful in any damn scenario in this world. (Apocalyptic).
If they needed one energy to produce another and if bitcoin goes as far as eating the world then
they will simply produce another technology with much smarter use of energy. I mean why one would keep using a tech if it's getting over their heads? We are intelligent species,
if did invent the bitcoin then we could do more than that if such apocalyptic scenario stumbles upon us.
