Ok, now imagine what a 384GHz core would cost.

(hint: probably more than the world GDP. Each)

Ok, NOW imagine what 10,000 3.84GHz cores would cost (100 times more aggregate cycles per second than 1x 384GHz core). What's that, you figure a measly $10-30M instead of more money than exists on earth?

Any research simulation is going to want to be parallelized anyway. You'll bump into the limits of the 384GHz core, no doubt about that, at which point you are back to distributed computing. For limitless complexity and limitless appetite for computing power, distributed computing will always be the answer.
