Ferroelectrics, a "new" non-volatile memory technology on today's scene, actually competed for the "core" memory of new processors in the 1950's. See the work of J. R. Anderson of Bell Labs: [ J.R. Anderson, "Ferroelectric Material Storage Element for Digital Computers and Switching Systems." Electrical Engineering, Vol. 71, pp. 916-922, October, 1952. ], Charles S. Pulvari of the Catholic University of America: [ AIEE-IRE '53 (Western) Proceedings of the February 4-6, 1953, Western Computer Conference Pages 140-159, ACM New York, NY, USA ©1953 ], and Dudley A. Buck at MIT: [ Dudley A. Buck, "Ferroelectrics for Digital Information Storage and Switching", Report R-212 a Master's Thesis, May 16, 1952, MIT ]. Their devices used bulk ceramic capacitors, not thin films so they required hundreds or even thousands of volts to switch the capacitors. Something old! Something new!

Memory and disk space will both expand to overflow existing technology. At the time Bill made his statement, few of us had ever used more than 64K bytes of memory. It was only after memory prices fell that the great explosion began. I remember when 8K by 16 bits cost $1/bit. Compare that to today's costs and you can see why Bill assumed the growth of memory would be limited. By the way, I have a 16K by 16 bit ferrite bead board framed in my living room as an example of the past example of memory technology.
