Between the theory that cybernetically augmented humans will become the "hard AI" of science fiction and signs that a cure for aging is nearly here, I would feel a lot more comfortable if we all started having a public debate about the limits we will set on metahumans. A cybernetically augmented human might gain an intelligence completely alien (and hostile) to us non-augments. And an immortal-except-for-catestrophic-accidents could amass an unseemly amount of wealth and control over non-immortals over their long lives - moreso than the elites of today could dream of. My concern about those that metahumans will hold such disproportionate power and they'll quickly get bored. Idle hands are the devil's playthings after all, and they could really make life difficult for the rest of us. I want to see what a many-hundreds of years healthy life will be like and live many lives, but I do not want to have implants or devices that warp my mind/memory. I want to stay human, just minus the frailties. I'm hoping that these evolving new technologies sort neatly into two buckets: those that enhance but still retain the essential (limited) human experience, and those that seek to obliterate and replace the human experience (so that I know which ones to avoid.)
