Well, even if we do **** things up, as long as mankind isn't completely extinct it will adapt and survive and rebuild, since adaptation and survival are quite possibly the two things we do best.
Actually, if we screw things up and decimate ourselves, the chances are that'll be it, we are, after all, living on a time-bomb, the only chance humanity really has is to get into Space and diversify (which may
require that we use this kind of knowledge, so it's a two-edged sword), setting ourselves back a few thousand years means that we have an extra few thousand years trapped on a single planet.
And Rodo, It's not really a question of 'control' as you put it, it's a question of responsiblity, which is something different. One step towards that may be getting the rules sorted out before we start, but the problem is, who defines those rules and who enforces them?
It's not really anything to do with what you are defining, which appears to be along the lines of 'just deal with it', that's an attitude that has landed us in so much trouble in the past, we could get away with it before, even with Nuclear theory, but the fact of the matter is, this isn't a question of 'morals' or 'Right/Wrong', it's a question of good old fashioned common sense, I'll agree that whether we are ready as a race for this or not, it's coming, so maybe we should start thinking 'what are we going to do about it?' before it explodes in our faces this time?
Growth is good, change is good, knowledge is good, idiots trying to turn it to their own agenda is bad, with things like genetics, this is
so vital to be aware of. Mistakes, at least, can be safeguarded against, political expediency is far harder.
