Disagree with Ferguson.
I worked with Cray-2 supercomputers at Norfolk Naval Ocean Processing Facility in the 1980s.
It occupied 16 square feet of floor space, weighed 5500 pounds and consumed 195 kW of power.
The fastest computer in the world at that time with a clock speed of 125 MHz.
My current home computer has a clock speed of 3300 MHz. Plus it is much smaller, lighter and consumes far less power.
Computer tech has advanced more from 1987 to 2012 than it has in all the time before.
Then you probably remember the first time you saw a CRT on someone’s desk.
Every single job in the country is done radically differently than is was 30 years ago. At least the ones that still exist and not including the ones being done no one dreamed of 30 years ago.
You think there will be a breakthrough for the next 25 years in computer tech?
