When I think of cyberization (or robotization, as op calls it), I think of how it was done in Ghost in the Shell: S.A.C.. In those regards, I can see where those kinds of things would be a very appealing idea. I don't mean I would personally completely cyberize like some may, but to some degree of cyberization could be helpful. I myself would like an upgrade to my reaction time, as well as an upgrade to my muscle reflexes (let's face it: without one, the other is rather useless). I don't believe that cyberization would lead to immortality - it may prolong your life, but there's only so much you can do before there isn't really anything left of you.
Oh yes. My ideal society would be a mostly abandoned earth inhabited by no more than a few million people, centralized government ran by scientists and engineers, with the sole purpose of advancing humanity through science. No soldiers, no priests, just people working on science and technology. The inevitable portion of people who are unwilling, too stupid or otherwise incapable of Contributing are responsible for physical labor.
That sounds like a combination of Umbrella, Shinra, and Cerberus all put together. I'm not so sure I'm comfortable with that.
