Friday, May 13, 2005The Total Information Available In The WorldMichael Lesk writes that the Web may be as large as the Library of congress. The Web has been growing 10-fold each year. Current estimates of the number of Internet users run in the tens of millions, perhaps 50 M, and this might grow to one billion; thus a factor of twenty is available by increasing the number of people on the Web. If assuming that people put more and more of their life online best estimated to be a factor of 20.This suggests that the amount of Ascii on the Web might increase to 800 terabytes.
