I note that physicists have frequently, throughout the last few hundred years, expressed confidence in their understanding of the whole universe ... and then been proven wrong by later generations of physicists...
Personally I find it highly unlikely that the current physical understanding of the universe as a whole is going to survive the next century ... especially with the Singularity looming and all that. Most likely, superintelligent AGIs will tell us why our current physics ideas are very limited. Fortunately, we don't seem to need to understand the physical universe very completely in order to build AGIs at the human level and beyond. -- Ben G On Thu, Oct 30, 2008 at 5:29 PM, Pei Wang <[EMAIL PROTECTED]> wrote: > On Thu, Oct 30, 2008 at 5:18 PM, Matt Mahoney <[EMAIL PROTECTED]> > wrote: > > --- On Thu, 10/30/08, Pei Wang <[EMAIL PROTECTED]> wrote: > >> So there are physicists who think in principle the stock > >> market can be > >> accurately predicated from quantum theory alone?
