I think that we have a tendency to allow big business to run with the benefits of science and they do not act responsibly. They put profit before people or the environment and do not put in sufficient safeguards.
Hopefully the massive leaps that will soon be coming with the harnessing of genetics and biochemistry in the fields of medicine, food production, materials, plastics, fuel and computing will be tightly controlled and regulated and the benefits shared among us all and not simply siphoned off by the wealthy.
