It appears that the most exciting prospect for the human race is the human brain and its connections to be decoded and ultimately replicated in a computer of a kind. This could indeed be our hope for immortality.
Of course, even if this happens some day (and the decoding is pretty much certain to happen sooner or later), we still don't know if or how the replicated brain will function inside a machine. Some sensory input can be simulated of course, but somatesthesia looks particularly tricky and without it we may not have a functioning brain at all.
But assuming those problems are overcome, or at least assuming that we can build machines that operate at the same (or higher) level of complexity as the human brain, then of course the possibilities are endless. At some point, those machines should be able to operate in the form of biological computers of extremely small size (molecular level probably) with minimal energy requirements, easily obtainable by solar or other "green" power.
A further understanding of the workings of the brain will then allow simulation of experiences a la Matrix, at a level where one could enter and exit the Matrix at will.
At that stage, there is no reason why the brains would remain individual. A global network of brains could be envisioned, where "I" and "We" would be the same.
Of course, exploring the space would be now feasible, since nothing could stop us, except maybe the end of the universe and time itself.
Such a nearly immaterial existence of humanity, will also need some way to manipulate the matter around it, at least in the beginning. This could be the age of sophisticated robots, although one can think of a later stage where such manipulation will not be necessary because even space travel will be happening with the help of light or other waves.
When you think of these possibilities, you might even imagine that very advanced aliens may be already living among us without communicating with us because they don't need to say anything to us.
I find such possibilities to be pretty probable, unless of course we manage to destroy the human race before technology advances sufficiently. What do you think ?
