Man-made computers are limited in their performance by finite processing speed and memory. So, too, the cosmic computer is limited in power by its age and the finite speed of light.
The minute hand moves faster than you think it does.
The microprocessor is a miracle.
We must see whether the same clock with weights will go faster at the top of a mountain or at the bottom of a mine; it is probable, if the pull of the weights decreases on the mountain and increases in the mine, that the earth has real attraction.
I'm convinced Apple has been doing the core/clock speed architecture right, while other OEMS are more caught up in this core count race that isn't really going anywhere.
The speed at which modern CPUs perform computations still blows my mind daily.
Anyone can build a fast CPU. The trick is to build a fast system.
