As you know, I love to point out the mistakes made by those who make future predictions. Since I was little more than a teenager, I have been saving clippings from the press and scientific journals that make more or less reasonable forecasts about the evolution of science and technology. In an earlier article I have pointed out that such predictions are seldom met, even when made by people who are both scientists and visionary, famous science fiction authors such as Arthur C. Clarke or Isaac Asimov.
I just unearthed an article published by Alexander Kusko in the IEEE Spectrum magazine in April 1968, with the following title:
A prediction of power system development, 1968 to 2030
And the following subtitle:
By predicting the trend of future power system design some 60 years hence, we should be better equipped to solve some of the technical and sociological problems that the industry faces today.
The assumptions on which Kusko's predictions were based were the following:
- The population will triple. What did actually happen? The world’s population in 1968, according to UN data, was about 3.5 billion people. The world population in 2015 was 7.35 billion. According to UN estimates, the world population in 2030 will amount to between 8.2 and 8.8 billion people. Far from the 10.5 billion estimated by Kusko.
