I augmented my eyes through a laser to take away the weakness I was born with. I was nearsighted. Now I am perfectsighted :)
Personally I'm really looking forward to the day when we reach even a fraction of what's in Deus Ex. Me and my workmates discussed this very topic a few days ago. We were talking about sportsmen taking drugs to enhance their ability and where the line was. I brought up the prospect of exchanging your limbs for stronger, faster and more durable parts. I don't know if there are any laws against it yet but it would be possible to cut off your legs and replace 'em with prostetics that make you faster. What is then the difference between taking drugs to enhance your abilities and replacing your limbs for the very same purpose?
It's an really exciting time we live in. If our race could get their heads on straight and stop "bickering" I don't see why we can't have colonized space (among other things) by the end of our generation :)
I think mankind will definitely reach a day when we take charge of our own evolution through bio mechanical engineering. The potential dangers are massive though, particularly the risks to society. There will be ethical divides, financial divides and ability divides. Human kind would likely by split into various sub sections that are unable or unwilling to co-exist.
@Ka113 Agreed, so many ethical questions and things to discuss, truly a must see!
