The Worldwide Computer
Monday, March 4th, 2002Scientific American reports: When Mary gets home from work and goes to her PC to check e-mail, the PC isn’t just sitting there. It’s working for a biotech company, matching gene sequences to a library of protein molecules. Its DSL connection is busy downloading a block of radio telescope data to be analyzed later. Its disk contains, in addition to Mary’s own files, encrypted fragments of thousands of other files. Occasionally one of these fragments is read and transmitted; it’s part of a movie that someone is watching in Helsinki. Then Mary moves the mouse, and this activity abruptly stops. Now the PC and its network connection are all hers. … Mary’s computer is moonlighting for other people. But she is not giving anything away for free. As her PC works, pennies trickle into her virtual bank account. The payments come from the biotech company, the movie system and the backup service. Instead of buying expensive “server farms,” these companies are renting time and space, not just on Mary’s computer but on millions of others as well. It’s a win-win situation. (03/04/02)
