You are showing that you have d not understand how these technologies work.
1. Large-scale space mining and colonization is decades to centuries away. Until we can defeat the tyranny of the rocket equation, it simply is not economical to try to do bulk industry in space. If
tomorrow we get some quantum-leap forward like a form of anti-grav tech that's reasonably cheap to build, that timetable could move up, but nothing less is going to accelerate it like that.
2. Automation cannot obsolete human labor. Not 'will have a hard time,' it
can not. It can make
specific kinds of human labor obsolete, as has already been demonstrated, but there are some things it simply cannot do, and even more it cannot do in a cost-effective way. Over time, gradually more and more things will become cost-effective, but as has been demonstrated over the last ~250 years, more work will always be found.
3. Large-scale use of cybernetics are still decades to centuries out, if they ever see mass-implementation at all. Simply put, the problem of man-machine interface still has not been solved. There's prototypes, there's experiments, and it's
looking like it probably
will be solved, but people have been expecting that to be available 'next decade' for forty years or more. We
might see limited use next decade, and bulk use the decade after that, but that's optimism.
4. Cybernetic 'augmentation' is science fiction. In fiction, 'man+machine=stronger' is a very interesting and useful theme. In real life, the human body is an incredibly sophisticated, capable, strong, resilient, self-repairing, cheaply-fueled, machine the likes of which no human engineer has even come
close to matching. Machines built for specialized purposes can be
much better than a human at fulfilling that function,
but adding the design requirement 'must be integrated into the human body' puts a
massive set of constraints and contradicting designs imperative into the project. Conversely, an external machine is much easier and cheaper to design, build, operate, and maintain. Plus you don't need to rebuild from just about scratch if the person the cybernetic is integrated into dies.
Cybernetics, realistically, will be inferior replacements for damaged or destroyed body parts. If we get extremely well-developed mind-machine interface, we might see things like mental internet-browsing and similar, but that's a different branch.
I don't disagree that there are people who'd
like to see such things happen, and exert such control over society. There is no
shortage of such would-be tyrants, but we're decades or centuries from that kind of cyberpunk stuff.
I write sci-fi, and I've done quite a bit of research into what the actual
practicalities of these things are, and how that contrasts with science fiction.
