WHY PEOPLE WILL WANT IT
Let's face it: the Memex 2015 will be the greatest medium for pornography of all kinds in the history of the world. If the estimates of use of the World Wide Web for pornographic viewing are accurate, then this factor alone will guarantee brisk sales for the Memex.
Aside from tawdry uses...the Memex 2015 will also facilitate telecommuting. As suburbs grow farther and farther away from the central city, highway commuting will become increasingly difficult. For knowledge workers, telecommuting will more and more become a viable alternative as bandwidth and home computing power increase.
