Recently the company nvidia which specializes in making graphics chips for PC and Game consoles got into the super computing business. Rendering graphics is very computationally intensive. If you look up the cost of computation on wikipedia you can check out these statistics.
1 gigaflop which equals 1 billion floating point operations per second cost $1,000 in 1990.
That same Gigaflop costs $0.42 in 2007.
The average American home is worth about $200,000. If your home had undergone the same economic transformation as supercomputing power it could now be replaced for $84.00. Just kinds of puts the growth in power of computation into perspective.
The same calculation using the human genome indicates a cost drop from $3billion in 2003 to an estimated $1,000 in 2010. Thus the cost of home replacement would be about $.065 in 2010.
That is a a lot of information power moving at an incredible rate. Who wins and who loses in that game has huge repercussions. Check out Ray Kurzweil's book the singularity.
