Hmm we're hitting limits to what can be achieved with 2D lithographic processes on silicon, although exotic negative refractive index materials may well allow lithographic techniques to be scaled to much smaller than the wavelength of UV. This means there will probably be a "bump" in store for Moore's law shortly. But we're still a long way from fundemental physics limitations. Where to from here? Probably the most obvious is the move to 3D. But that direction will bump into thermal limits pretty soon, as a 3D object tends lower surface to volume ratios. So the answer will probably need to involve exotic materials - maybe Gallium, or maybe the memristor stuff HP is working on. Or organic transitors. There's any number of ideas in the research lab, that might be the successor to current VLSI technology. >However, it's really a subsidiary point.

Most of the machine learning algorithms (our most succesful AI algorithms) are quite parallel as it is. Do you really think the learning algorithm behind Google's language translation tool runs as a single process task?

There is a simpler task that doesn't involve qualia (unless you happen to be a creationist). Create a creative evolutionary system that mimics biological evolution in continuously creating new solutions to problems. I suspect that once that problem is understood, the step to genuine AGI will be rather short. Of course, we'll probably still be arguing over whether those AGIs are conscious or not, but as Brent notes, maybe that particular question will then become uninteresting... -- ---------------------------------------------------------------------------- Prof Russell Standish Phone 0425 253119 (mobile) Principal, High Performance Coders Visiting Professor of Mathematics hpco...@hpcoders.com.au University of New South Wales http://www.hpcoders.com.au Latest project: The Amoeba's Secret (http://www.hpcoders.com.au/AmoebasSecret.html) ---------------------------------------------------------------------------- -- You received this message because you are subscribed to the Google Groups "Everything List" group.
