This can be seen in history; in the way humans spread around the Earth, moving to new lands, new environments and overcoming incredible odds during those times. Those early pioneers found a way through, they returned, were able to convince large numbers of others, and they were correct, though many tried and failed and did not return as well.

Also the problems that gravity presents seem like a deal breaker even with a new, incredible energy source. Keep working on the breakthroughs. Then the shift will come. With or without the migration of humans to the rest of the Solar System, bio-engineering will happen.
Book Review: Emigrating Beyond Earth
Certainly, expansion and exploration could take place without it and it would offer those Donner Party type of moments. With it, it enables more migration and adaptability. I would add that what makes a triad is artificial intelligence that we will realize out-performs us in many respects. My recent comment here reflected on this challenge.
We will be defeated by A. Any culture that has been defeated technologically has survived by embracing and often reviving their cultural heritage.
- Space colonization - Wikiwand?
- Oh no, there's been an error.
- Read Books Emigrating Beyond Earth: Human Adaptation and Space Colonization (Springer Praxis.
- Incidents in the Life of a Slave Girl.
- Global Order and Global Disorder: Globalization and the Nation-State?
So it will be for all humanity. Technology even without A.
Emigrating Beyond Earth : Human Adaptation and Space Colonization
Few people are going to fit that description compared to society as a whole. A comment here mentioned the need for major technological breakthroughs. The moon landings did that, for a time, until the pendulum has swung back toward narrow interests. I should add that the review is a good one and it pulls no punches and states what is lacking which is along the lines of my first comment. Also, raising questions and comments from readers is a good thing.

We've known since the s that space is no place for humans, and that the only way we'll ever be able to survive up there will be through radical morphological modifications. The entire field of cybernetics was predicated on this underlying assumption — and nothing has changed in the 60 years following its advent.
Moreover, Darwinian selection is slowly but surely being decommissioned, replaced by intentional design. In addition to cybernetics, we will modify ourselves and adapt to our environments by using advanced genomics, synthetic biology, and nanotechnology. And should we encounter any problems — which we surely will — we can use these same technologies to adapt on the fly. As we wrote earlier this year :. Nanotechnology expert Robert Freitas has outlined a plan for the elimination of lungs, making breathable air unnecessary.
Ray Kurzweil has speculated that future humans won't require food, equipped instead with nanobots that can energize our cells.

And even Craig Venter has chimed in, putting out the call to develop an advanced inner ear that can allow people to escape motion sickness, genes for bone regeneration, and DNA repair for radiation He's also suggested that we develop a small stature, higher energy utilization, hairlessness, and slower skin turnover. And yet others have speculated about transforming humans into gangly octopus-like creatures who would be far more adapted to slithering around in zero gravity environments.
But relying on "random mutations," as Smith suggests, is completely ludicrous. We will be the ones in control of our genome, and not the whims of Darwinian processes.

Our ability to live and work in space will not be a subtle thing, and not something that will come about after tens of thousands of years of agonizingly slow evolution. Thinking even more conceptually, there's even the possibility that we'll have to become completely postbiological to survive long-term in space.
This could entail our complete transformation into cyborgs, or as Giulio Prisco recently argued , as uploaded entities. Both biology and culture will evolve beyond Earth. Genetic studies tell us that we must be numerous and diverse in such migrations, and cultural anthropology shows that while we cannot predict precisely how humanity will change, we can be sure that it will, in universal concerns including how we measure kinship, our rules of inheritance, gender and age categories, and how we structure our families.
There is plenty to consider. We might as well begin now. Propulsion systems are being designed by the physicists at Icarus Interstellar.
