Sentient computer artificial intelligence (AI)
would appear to be the next evolutionary step.
And what could a sentient AI do for humans?
By manipulating physical reality at its
fundamental level (which is mathematical
process) such an entity(s) could give all
humans Heaven, forever young, forever happy.
I have written a book which considers this
idea. The first 2 chapters, AI Heaven and
Spiritual Heaven, can be found in issues 1
and 3 of the online magazine, Alma, at
