I had been impressed by the fact that biological systems were based on molecular machines and that we were learning to design and build these sorts o…

Protein engineering is a technology of molecular machines - of molecular machines that are part of replicators - and so it comes from an area that al…

I've encountered a lot of people who sound like critics but very few who have substantive criticisms. There is a lot of skepticism, but it seems to b…
