ACM 97 I think there is a world market for maybe five computers. Thomas Watson Senior, Chairman of IBM, 1943
ACM 97 Predictions require some history. The computer hadnt been invented. Watsons prediction held for 10 years. You need history to predict.
ACM 97 Navy Delphi Panel 1969 Card readers will peak at 1500 cards per minute by 1974 and then their use will decline. Advances in cores, wire, and thin film will provide large memories with one million words by 1976.
ACM 97 Ill bet well be manufacturing cores in 1980. H. Lamire VP Manufacturing, Digital 1975
ACM 97 A technology can come from nowhere and wipe you out! MOS memories and micros were introduced in 1972. By 1976, MOS memories wiped out core memories.

ACM 97 For short-term predictions, bet against the optimist. They are likely to be wrong. Longer term, science-based predictions have a good chance... wait 11 years (Meads Rule) Organizations usually behave poorer than anyone can predict
ACM 97 Gordon Bell Future of Computing at MIT, 1972 Future computers are BOTH cheaper AND faster model posited Semiconductor companies may make the computers We need networks, else people are the network that serve computers Semiconductors (bipolar) just improve for 6 more years
ACM 97 Progress will continue for just 6 more years! One generation beyond the product being worked on If you are actually doing it as an engineer... you tend to be very conservative
ACM 97 Everything cyberizable will be in Cyberspace! Gordon Bell and Jim Gray ACM, 1997
ACM 97 Outline Cyberspace: platforms, networks, and cyberization Some Laws from failed predictions Useful exponentials for prediction Computers we might predict
ACM 97 Cyberization: interface to all bits and process information Coupling to all information and information processors Pure bits Bit tokens State: places, things, and people State: physical networks
ACM 97 Everything will be in Cyberspace Is this a challenge? Our goal? Our quest? or Fate? Cyberization enables new computing platforms that require new networks to connect them – Infrastructure supports the content – Three evolutionary dimensions

ACM 97 Some more Laws from failed predictions to guide the journey into Cyberspace
ACM 97 There is no reason anyone would want a computer in their home. Ken Olsen President, Chairman and founder of Digital, 1977
ACM 97 Weve got the hottest machine at the show … IBMs entry really was disappointing. Digital KO aka Pro Manager, NCC 1981
ACM 97 Ethernet is much too elegant to be a commercial success. Ken Olsen 1981
ACM 97 Speech predictions are optimistic and have been wrong. Mobs and especially committees predict poorly.
ACM 97 ISDN will be ubiquitous by 1985. Irwin Dorros, VP Long Lines ATT, 1981 Unfortunately, ISDN is still likely to become the ubiquitous connection, by default, for the next 5 years. Gordon Bell, ACM 1997
ACM 97 Network bandwidth becomes available slower than the most conservative prediction.
ACM 97 We under-estimate the devastating power of companies & planners, lawyers & government, to foul up predictions. But to really foul up requires an econometric model!
ACM 97 Parallel processing computer architectures will be in use by 1975. Navy Delphi Panel 1969
ACM 97 In Dec. 1995 computers with 1,000 processors will do most of the scientific processing. Danny Hillis 1990 (1 paper or 1 company)

ACM 97 Parallel processing is a constant distance away. Our vision... is a system of millions of hosts… in a loose confederation. Users will have the illusion of a very powerful desktop computer through which they can manipulate objects. Grimshaw, Wulf, et al CACM Jan. 1997
ACM 97 Predictions are easy… especially about parallelism. Doing is hard. Predictions about parallelism were risky… now they are predictable.
ACM 97 Vannevar Bush c1945 There will always be plenty of things to compute... With millions of people doing complicated things. memex … stores all his books, records, and communications, and... can be consulted with speed and flexibility Matchbook sized, $.05 encyclopedia Speech to text Head mounted camera, dry photography

ACM 97 Build it and they will come Vision: Provide bandwidth and they will come to share supercomputers, do telemedicine, telescience, ship pictures around. Traffic continues to double. The web was serendipity! "A user... would build a process and launch it into the network... with explicit instructions about things to look for and what to do …."
ACM 97 Computing and communication predictions: processing, memory, and networks

ACM 97 VAX Planning Model 1975: I didnt believe it The model was very good – 1978 timeshared $250K VAXen cost about $8K in 1997! Costs declined > 20% – users get more memory than predicted Single user systems didnt come down as fast, unless you consider PDAs VAX ran out of address bits!
ACM 97 Computers by price are stable. Lower priced computers form! new models come at constant price and increased effectiveness constant performance, lower price computers come and establish new use
ACM 97 The mainframe is dead! … and for sure this time! PRICEPRICE Mainframe Server PC
ACM 97 The computer will not replace the book... digital media are not alternatives;... the interrelationship of modes of communication is... shaping public knowledge. Peter Lyman, UC/Berkeley 1996 Daedelus: Books, Bricks, and Bytes
ACM 97 Avoid absolutes in predicting technology … use may, could, almost Books arent so great. One can imagine an economy and technology that enables their replacement by 2047 GBell, ACM97
ACM 97 Predictable computers The network computer System-on-a-chip industry Home Area Network Body Area Network: on body, Guardian Angel
ACM 97 Observations on predicting Existence proofs are essential, otherwise its faith and luck. Numbers and data are our friends. Bet on predictors who are grounded, intuitive, imaginative, and lucky. Because it could, doesnt mean it will. Its usually just the economics, stupid!
