"The idea that we can control these unimaginably complex genetic encodings and ecosystems is like believing we can control the weather. Yes, we can affect it, but we can also certainly make it worse. We have no reason whatsoever to believe that we can engineer a perfectly desired outcome or fabricate a flawlessly designed product 100% of the time. It only takes one mistake, slipup, inadvertent human error to set us on a disastrous orbit or flight path."
