Foresight Institute is having a meeting described at http://www.foresight.org/SrAssoc/99Gathering/index.html to brainstorm about the next 30 years. Participants include nanotech gurus like Drexler and Merkle, our own Max More, other extropian faves like Vernor Vinge, Ray Walford, Doug Lenat, Marvin Minsky and many other famous names.
The conference is expensive; you have to be a Foresight Senior Associate which requires a pledge of $250 a year, plus it's then another couple of hundred to attend the conference. Still it does sound like it would be a fascinating and stimulating weekend.
