Tell you what scares me: Bionics.
Atm, they are miracles, or science over nature, but soon we're gonna start thinking:
"Bioni arms are better than normal arms." "Bionic eyes can see in the dark better than my normal eyes." "A bionic brain would help me pass my tests."
Soon we wont be human, we will be cyborgs, driven by our passion for perfection. Thankfully i will be dead by then
