Forbes has posted an interview with Bernard Meyerson, IBM's chief technologist, on the future of chip evolution and exactly how far Moore's Law can be bent. It's pretty heady stuff. Here's what Meyerson sees immediately happening, within the next decade:
The behavior of semiconductors goes quantum mechanical when you get down to 10 nanometers. After that you have to do nuclear fission, which is not something I want to be around to see. But Moore's Law, if you want to change its meaning, is completely extensible. Gordon Moore said that you can double the amount of stuff on a chip in a certain amount of time. People have always interpreted that as doubling the amount of stuff in a unit area. The reality is we're going to go to vertical integration and chip stacks. The amount of stuff per square-unit area is going to double.
Admittedly, a lot of Meyerson's interview is way above my head, but he talks a lot about moving on to 3D chips, light-based computing, unlimited caches and "entire planes of super high-density memory right above a plane of logic." This impresses me, since as stupid as I am, I do know that they are all critical components of a Timecube.
