Fabric of Reality (book cover link)quote:
A new, integrated and rational world view based on four main strands:
Quantum physics and its many-universes interpretation
The theory of evolution (Darwin/Dawkins)
The theory of computation (quantum computation)
The theory of knowledge (Karl Popper), explanation and understanding
some content links and some commentary on the bookHe argues that quantum computation, a discipline in which he is a pioneering thinker, has the potential for building computers that draw on their counterparts in parallel universes; this could make artificial intelligence a reality, despite Roger Penrose's objections (which Deutsch deals with in some detail). Likewise, time travel into both the future and the past should be possible, though not in quite the form envisioned by science fiction writers; the trips would almost certainly be one-way, and they would likely take the travelers into different universes from the one they began in.
A review contra what I think.
