The news that Michael Crichton has a new book out – State of Fear – reminds me that it wasn’t long ago that we were all worrying that mobs of anxious citizens would be pouring out of cinemas with a horror of nanotechnology induced by the film of his previous novel, Prey. But after a flurry of reports at the time that the film rights had been bought by Fox, even before the novel came out, there seems to have been nothing but silence. Meanwhile environmentalists are cheerfully getting on with their protests against nanotechnology regardless. And who are the villains of the latest Crichton blockbuster? These very same environmentalists, with their irrational opposition to global warming. Now I’m really confused.
