If Homo Sapiens gave me a few different and deeper perspectives about humanity, then Homo Deus really stretched my big picture systematic thinking mind into different orbits.
I can cery well see some of the scenarios discussed here come to fruition- in fact I see many of the trains having left the stations already.
If anything, the book assumes to have figured out consciousness as a mere emergent property of complex networks and algorithms for which the scientific community has no consensus yet. The possibility that human computational powers extend still deeper than the presumed smart algorithms of the future cannot be discarded. In fact, that seems to me to be our only hope of survival as a species.
Excellent book! Really excellent!!
