"virtually omnipotent"? I think that a high technology civilization that retains social conflicts will destroy itself - and this is happening on Earth right now.
In The Golden Age, two guys, for this purpose let's call them A and B, spend a pre-agreed period of time swapping memories, sharing experiences and living each other's lives. At the end of the agreed time, B refuses to believe that he is not A and takes measures, using mental technology, to drive himself further into this illusion and away from reality. But, given these premises, how can A be sure that he is A? He has evidence and testimony that he is who he thinks he is but how does he know that his experience of this evidence and testimony is not illusory? He may have elaborately deceived himself as (he thinks) B has done or someone else may be deceiving him. With a technology that could make every member of a global population healthy, wealthy and wise, powerful individuals and composite mentalities play spiteful tricks on each other and both the reader and the characters get confused. The novel could climax with the realization that none of it has happened.
I am rereading two thriller writers, will shortly start The Sunrise Lands by SM Stirling hope to get Poul Anderson's Murder In Black Letter as an ebook.
Addendum: OK. Technology alone can't make us "wise." I was just using that expression, "healthy, wealthy and wise." But human beings are social as well as individual. A transformed society will generate a different kind of individual.
