Now we have technology where we can modify the genomics of individuals by gene transfer and genetic meddling, we may find that people will want to modify their children, enhance their intelligence, their strength and their beauty and all the other so-called desirable characteristics.

I think it's important for scientists to be a bit less arrogant, a bit more humble, recognising we are capable of making mistakes and being fallacious - which is increasingly serious in a society where our work may have unpredictable consequences.

You can now modify the genes of large animals, and the largest animal we are concerned with is the human.
