At the Southwest Fox conference, I showed a slide titled “My Toys”

I showed the computer, the processing speed and the amount of memory in a table:



Year     Machine           CPU Speed       Megabytes        Product (Mhz*MB)

1971     PDP-8              .066                  .004                  .000264

1981     IBM PC             4.77                  .25                    1.1925

1991     PC Clone          66                     1                      66

2005     TabletPC           2000                 2000                 4,000,000



Both the processor speed and the RAM increased by several orders of magnitude over the decades. The Speed Memory product of my current tablet is 10 billion times (LOG10(4e6/.000264) => 1e10)greater than my first machine!


At this rate what will a machine look like in 10 years?


In comparison, a 747 Jet has about 40,000 horsepower,  and a human has about 0.17 horsepower, so a jet is only about 2e5 times more powerful than a person.

BTW, on another slide I showed a photo of the salmon painted plane I flew to Phoenix: “…among the world’s most intricately painted commercial airplanes”
