Stephen Hawking Engineering Quotations

Nuclear weapons need large facilities, but genetic engineering can be done in a small lab. You can't regulate every lab in the world. The danger is that either by accident or design, we create a virus that destroys us.

It should soon be possible dramatically to increase the intelligence and life span of a few individuals [with the help of genetic engineering]. They and their offspring could become a master race. Evolution pays no regard to social justice. It was not fair on the Neanderthals they were replaced by modern humans.

One is always a long way from solving a problem until one actually has the answer.
