wut? I thought that would be in the millions of years, if not more, timescale.
OP: No idea. It's incredibly hard to predict something like that when the scale is 5000 years in the future. I think as soon as we invent truly intelligent AI, it's impossible to predict (singularity). If I had to give an answer, though, I'd say extinct.
EDIT: I take extinct back. I think if we can at least get to Mars and get it colonized (well, we CAN now if we wanted to), we'll be ok.
Once sentient AI is developed, and it's capable of refining itself, we may well become obsolete. But of course, where we go from there depends on how the AI was "raised" - as a military AI, intended to kill things, or something more on the benign/benevolent side? It very well will not have the same requirements or ambitions as us, and it may be perfectly fine with leaving us alone, or even finding some other planet to live on, likely in order to escape destruction at the hands of easily-frightened primates that don't like competition.
Or else it will take after us, and decide to destroy the biggest threat to its own existence. Then it becomes the dominant sentient being on the planet.
Where would our technology go? Hopefully there'll be some means to keep our instinct ahead of our destructive tendencies. Advanced biological weapons, nanotechnology, powerful explosives...all in the hands of a species whose history is one of
constant and nearly unbroken fighting and cruelty.
But geez, where could it go besides that? How many things do we have now that were "impossible" 200 years ago? Even shooting for 1000 years from now...so much time.
- Nanotech/cybernetic type augmentation of all major body systems, to the point where the organic components are nearly antiquated in function.
- Aging is effectively stopped, since cells and components can be easily replaced on-the-fly.
- Death of a body occurs only by rare accident, or by choice; death from simple old age is viewed as an ailment of olden times, a result of the crude method that evolution came up with for keeping life going in a hostile environment.
- Development of the ability to "back up" minds leads to the ability to duplicate them. This could be especially interesting, as you could suddenly make new sentiences (yeah, I'm making it a word) in a few minutes. Talking to yourself isn't enough? Now you can form a committee.
- Robotic resource gatherers in the asteroid belt and small moons throughout the Solar System, retrieving particularly useful materials.
- Room-temperature fusion - either by discoveries in physics that enable the neutralization of the repulsion between atoms, or by redefining "room-temperature."
-
Everything is a networkable device, part of whatever the Internet is by then.
- We will still be using IPv6.
- FTL communications linkup with sentient probe flotilla orbiting Wolf 359. They never do find any avidence to support the ancient-aliens story of a massacre by cybernetic humanoid invaders.
