Nanotechnology, K. Eric Drexler and me

Next week – on the 26th March – I’m participating in a discussion event sponsored by the thinktank Policy Exchange at NESTA, in London. Also on the panel is K. Eric Drexler, the originator of the idea of nanotechnology in its most expansive form, as an emerging technology which, when fully developed, will have truly transformational effects. It will, in this view, allow us to make pretty much any material, device or artefact for little or no cost, we will be able to extend human lifespans almost indefinitely using cell-by-cell surgery, and we will create computers so powerful that they will host artificial intelligences greatly superior to those of humans. Drexler has a new book coming out in May – Radical Abundance: How a Revolution in Nanotechnology Will Change Civilization. I think this view overstates the potential of the technology, and (it shocks me to realise), I have been arguing this in some technical detail for nearly ten years. Although I have met Drexler, and corresponded with him, this is the first time I will have shared a platform with him. To mark this occasion I have gone through my blog’s archives to make this anthology of my writings about Drexler’s vision of nanotechnology and my arguments with some of its adherents (who should not, of course, automatically be assumed to speak for Drexler himself).
