Only questions but no answers. The dirty secret is that Utopia can exist. It does exist. Soon these little Utopias may conquer death, itself or at least continue to postpone it farther. But, it can't be Utopia for all.
My life if something of a tiny utopia. So, I don't see any way that thinking creatures can have a metamorphosis. We already sqeeked thru a bottleneck of genetic doom and are really just a family gene pool, the species died out long ago. There is not enough genetic diversity to allow much more much evolution, I don't think.
The very mind we use to visualize these utopias is the very mind that makes the past, for example, seem better. More simple.
Some seem to think progress was forced by capitalism. Some think we are ruining the world, killing the planet. No, the planet is still killing us.
We got here because we stopped evolving. If you think these Green Verdant Jungle Edens were Utopia...only because their existance was stalled in place for 1000s of years. Oh, yes, a mindless utopia. Totally bound by taboo and the crazy old shaman. Life arranged, and taught not to think, at all, feel the forest and be ready to roll off a big cat from your back. Survival static utopia. Bound and gagged to the tribes ways, or shunned.
We get to espouse all these theories, --sm this and -ism that, only just recently did we fight and give ourselves free speech. And the world benefits. But Sharia claws are sharp. It is still ALL a simple cloak for the ways of power.
I have Utopia. I defined it, I created it myself. I keep it going and keep my dumb ass alive in it while I can. I had the luck of the draw and so did our President. Hierarchy will crush all silly theories into a horrid mess that has shown to lead to blood.
Best just accept the mind can come up with much more than is possible.
