The Singularity is Near. It came out more than 2 years ago, but I've just started reading it. If you've mindfully noticed how technology keeps improving while lowering in price, then this is recommended reading. Video game systems are a good example. One may reasonably conclude that my example is not good, since the prices of game systems have gone up, but an XBox 360 (assuming it was possible to manufacture one) would have cost more than an F-15 if it had been released alongside the NES. So the prices have actually dropped by prodigious amounts.
Assume that a video game system is a tool, like a shovel. For many hundreds (possibly thousands) of years the shovel did not improve. One would use the same shovel throughout the entirety of their lives, possibly passing it on to their progeny (or apprehended by them). If the NES were like a shovel, then we'd still be using it, as would our progeny - and theirs, for many generations. Just in my lifetime, I've seen the invention of many new shovels, each one more powerful than the last - and vastly cheaper. Imagine for a moment how many times the computing power the Xbox 360 has over the NES, and then multiply that amount by the original cost of the NES.
F-15 fighter jets cost around $30,000,000 each. I don't know the processor speed of the XBox 360 or the NES, but if I assume the 360 does a gigaflop and the NES does a tenth of a megaflop, then the 360 has 10,000 times the computing power of the NES. I don't remember how much the NES cost when it first came out, but I'll guess $300. Since the 360 has 10,000 times the computing power of the NES, it would've cost $3,000,000, which is one order of magnitude below my estimate of $30,000,000.
