The second miracle is the infinite-demand elasticity associated with the Big Three. It works like this. When speed or memory prices drop, computers consume more of the good stuff and, hence, get more powerful. A thousand software developers, from giant Microsoft down to the guy or gal in a garage, immediately begin writing code that takes advantage of the new powers. Thus do speed and memory pave the way for new or better software.
Software always soaks up chip power.
Take it to the bank. Software always soaks up storage and pipes, too. No doubt the MIT Media Labs can tell you the specs required and the month and year this marvel will arrive. They double speeds or memory capacity at the same price-point every 18 months. Storage devices double every 12 months.
