Seriously I have to disagree, Shannon.
We're likely about 3 to five years from full visual/auditory VR becoming commonplace. Probably less than ten from full cybernetic replacements of arms and legs. A full body replacement is probably no more than 25.
I study emerging technology. I especially study prosthetics. In the last year I have seen some incredible technological advances in these fields.
Rebuilding my entire body from scratch is going to take a few decades, but I expect it by 2035 or there about.
Considering the emerging technology to create entire cloned organs on demand, which I forsee being viable by 2020, a lot of cosmetic surgery that is impossible today will be far more possible by next decade.
I actually foresee becoming a Virtual Persona first, an Avatar overlaying my normal appearance in augmented reality displays. By the mid twenties, I see having my hips widened somewhat (much easier that replacing my entire upper body) with a chromosome switched cloned vagina and uterus, a cybernetic tail attachment, prosthetic hooves and wings, and artificial rams horns. Breasts will be a mix of stem cell enhancements and hormones, teeth and ears simple cosmetics, and improved variations of standard plastic surgery to take care of other details.
By 2035, I will be able to reshape the prosthetics into actual genegineered clone limbs.
By around 2040, I MIGHT be able to create a fully genegineered clone body to which a full brain transplant could be possible, but I would not want to be a early adopter of such tech. So maybe by 2045.
And this all presupposes that fully functional nanotechnology isn't perfected within that time frame.
Genetic engineering is going to advance by leaps and bounds over the next decade, to the point that DNA will become the equivalent of a programming language. Gene modeling is going to become something computers can render and prototype prior to actual synthetic organism creation within about 15 years. It will start with bacteria, and grow into more complex systems over the next decade following. It might happen faster than that, it might take longer.
We are too close to "cyberpunk" style cybernetic prosthetics right now to find a 700 to 1000 year timeline realistic. At WORST case, 30 to 40 years would be probable, with my estimate, based on the pace of development over the last ten years, to be 10-15.
Technology doesn't really care much about the pace of social change. Considering how much it has forced us to adapt in just the last ten years, social change is going to be forced on us for good or ill. I happen to think it will be good, but it will still be extremely tumultuous, and very bewildering for those who don't understand what is happening. The Republican party is suffering from this sort of disorientation right now.
I once thought nanotech would never happen in my lifetime. that was twenty years ago. Now I see new developments on a nearly daily basis. As a computer tech, just the developments in the last five years have become hard to keep up with. We are about the hit the knee on so many technological curves I can barely keep up and this is something I spend some part of every day tracking.
I started out as a sci-fi writer too. I set my story almost a million years in the future, but had to abandon that, because in studying the advances in science, I came to realize I couldn't even make realistic predictions for a hundred years from now or even fifty.
Culture changed slowly because only a small percentage of the population was advancing knowledge rather than living hand to mouth existences. When we institutionalized science, we tossed that slow pace out the window. We have hundreds of thousands of scientists for every one that existed just a hundred years ago. And we have a population at large of non specialists who can devote time to hobby research who also make enormous contributions to our knowledge base. That effectively makes for a compression of progress that is thousands of times faster than it has ever been in all of established history, with that pace growing daily.
