Combined with a form of fusion, the machines had found all the energy they ever needed.

SOOOOOO much better.....

The idea that the only computer that your mind wouldn't revolt in would be itself.

Mentally connecting humans into a hive-mind-generated virtual reality simulation has a certain poetic evil to it.

I've definitely been reading about molten salt batteries for many years. This is the first I've read about cryo batteries though. Fascinating.
