Digital designers (of CPUs)—is Moore's Law really a self-fulfilling prophecy? Or is it just a business thing, where the only way to get people to buy a new computer is to make it faster (or "faster")?

Like, we don't have Moore's Law for cars—cars might have some dimension that could see exponential growth for decades (fuel economy? speed? um, size?) but probably not.

But is there a Moore's Law for financial transactions? Visa, bank wires, stock/futures/options exchanges, M-Pesa, etc.?
