A lovely 'Utopian' world seems quite nice. A place in which our technology has evolved to the point in which we no longer have to battle one another, and have thrown off the 'shackles' of religion to me seems grand. My problem with this type of 'utopianism' is that there is no room for the people who see religion as a 'freeing' concept, not one of shackles. But as long as there is a religion that says that all other religions are wrong, there will be disagreement. I'm not so shallow as to say that 'No matter what, people will fight,' but there will be disagreement.
I've recently developed, (but not polished) a theory of ethics/morality that I like to call the 'Realm of Intolerance.' This is almost a subjectivist theory of ethics, but it describes a universal: we can all be offended to the point of 'action' by other's behavior. At what point do each of us throw our own safety to the wind to stand up for a principle? This is the subjective part. The fact that all of us have it is universal. If I were to see a person smack their child on the bottom, I will not be moved to act. I will silently judge, but the fact that this offensive action does not in turn cause an action on my part means that I condone this behavior on some level, and is thus not a part of my Realm of Intolerance. However, if I saw a woman being raped in an alley, I would attempt to help her, at great risk to myself. Rape exists in my 'realm of intolerance.'
Granted, I do hope that people learn to develop free energy and solve the 'limited resource' problem that's been plaguing our species, (nay, all cosmological systems) since the beginning of time, at which point I would hope that the arbitrariness of others' religious beliefs would become apparent. At this highly improbable point in the future, I could see the previous gentleman's vision for the future becoming real. Throwing off the 'shackles' of religion is hardly a solution for those who love their religion, but being tolerant of others' religion seems universally beneficial, regardless of our state of technology.
On a less optimistic side of the future spectrum, I do see a sort of 'Cyberpunk' future coming soon. Everyone dropped cyberpunk like a bad habit once the year 2000 hit, probably because all of those cyberpunk writers of the '70s and '80s predicted extreme economic, sociological, and political change by the year 2000. Given that this didn't happen, I bet that people thought it never would. Well, if Mighty Capitalism keeps marching forward the way it is, cyberpunk is still a possibility. A future where corporations rule with an iron fist, and combat one another through espionage and all-out war. 'The West-Coast States of McDonalds.' 'The Pepsico Southern States,' etc are possible in that future.
There is an inevitable clash between this type of world and the Communist/Totalitarian future. (this world is set forth in the cautionary tales of Orwell, Bradbury, and Huxley)
To find a medium between the two types of rule, or, heaven forbid, a completely new idea of rule, seem exceedingly unlikely.
Pick your poison, boys and girls, for we drink 'till the Sun goes down.
