On the molecular scale, you find it's reasonable to have a machine that does a million steps per second, a mechanical system that works at computer s…

In a sense, artificial intelligence will be the ultimate tool because it will help us build all possible tools.

It's a lot easier to see, at least in some cases, what the long-term limits of the possible will be, because they depend on natural law. But it's muc…

Plants with leaves no more efficient than today's solar cells could out-compete real plants, crowding the biosphere with an inedible foliage. Tough o…

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…

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…

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…
