The world is already pretty multi-core. I was recently spec'ing out a high-end system for simulation work. You can now get Intel Xeons with up to 14 cores now, and soon 18. Talking about 36 high-end cores (dual-socket system) used to be the realm of Sun E10Ks and other very expensive systems. This is amazing to me.
