The Internet Configuration Control Board was established in 1979. In the early 80s, the Internet was well on its way. Academia was already using the network, and the writing was clearly on the wall with the World Wide Web going public in 1991.
Mark Twain predicted an Internet as early as 1898, Jules Verne in 1864. H.G. Wells described the concept of a World Brain in 1936-38.
As a science fiction writer, L. Ron Hubbard was well accustomed to painting predictive futures through his books. He presumably had access to countless earlier space civilizations to draw predictions from through his auditing of previous lives. He describes several earlier civilizations in detail. But no Internet.
Hubbard did not devise any policies or plan describing how his Church of Scientology should handle the imminent World Wide Web before he died in 1986. No PR plan, no clear path showing his followers how to deal with the upcoming fall-out.
The Internet spelled the downfall of Scientology. Hubbard missed the one thing that would eventually destroy his legacy. How come he left his church clueless in this area?
