Now, beginning by thinking where we want the world to be —which, by the way, is what this country’s Founders did when they put copyright into the Constitution in the first place: “to promote the progress of science and useful arts”—is useful but limited, because to get the desired situation in which we can aggregate with abandon, we need the original sources to survive.

Cache Memory
Cache memory is extremely fast memory that is built into a computer’s central processing unit (CPU), or located next to it on a separate chip. The CPU uses cache memory to store instructions that are repeatedly required to run programs, improving overall system speed. The advantage of cache memory is that the CPU does not have to use the motherboard’s system bus for data transfer. Whenever data must be passed through the system bus, the data transfer speed slows to the motherboard’s capability. The CPU can process data much faster by avoiding the bottleneck created by the system bus.
