When I started writing I did have some idealised notion of my dad as a writer. But I have less and less of a literary rivalry with him as I've gone on. I certainly don't feel I need his approval although maybe that's because I'm confident that I've got it.
Protein engineering is a technology of molecular machines - of molecular machines that are part of replicators - and so it comes from an area that already raises some of the issues that nanotechnology will raise.
