Albert Einstein ( 1932 ) “ There is not the slightest indication that nuclear energy will ever be obtainable. "

Lord Kelvin ( ) “ X-rays will prove to be a hoax" “ Radio has no future. " “ There’s nothing to be discovered in physics today. "

"I think there is a world market for maybe five computers." Thomas Watson IBM Chairman (1943 )

``There is no reason why anyone would want to have a computer in their home.” Popular Mechanics, 1949 ``Where… ENIAC is equipped with 18,000 vacuum tubes and weighs 30 tons, computers in the future may have 1,000 vacuum tubes and perhaps weigh just one-half ton.” Ken Olsen, President of Digital Equipment Corporation, 1977

“Computing power doubles every two years." Gordon Moore Intel Co-founder (1965 ) Moore’s Law Moore’s Law

Exponential Growth First commercial computer 1950: 100,000 additions/sec First commercial computer 1950: 100,000 additions/sec Fastest computer in 2000: 2.1 trillion additions/sec Fastest computer in 2000: 2.1 trillion additions/sec Factor of 21 million Factor of 21 million Comparison: Comparison: First airplane 1903: 10mph First airplane 1903: 10mph Fastest today: ~ 2500 mph Fastest today: ~ 2500 mph

Exponential Growth Exponential growth example: doubling every year. Exponential growth example: doubling every year. Would you take a job where your salary started at $16/year and doubled every year? Would you take a job where your salary started at $16/year and doubled every year? 2 years $64/year 10 years: $16, years: ~ 17 million 25 years: > 500 million This is what happened in the computer industry!

Aside: exponential growth is not unique to computer technology -- happens whenever the rate of increase of a quantity is proportional to the size of the quantity Aside: exponential growth is not unique to computer technology -- happens whenever the rate of increase of a quantity is proportional to the size of the quantity Other examples: compound interest, unconstrained biological population growth.

“In medicine, the computer, which started by keeping records and sending bills, now suggests diagnoses. The process may sound dehumanized, but in one hospital … a survey of patients showed that they found the machine ‘more friendly, polite, relaxing and comprehensible’ than the average physician.’” “In medicine, the computer, which started by keeping records and sending bills, now suggests diagnoses.
