This ad from the late 1970’s imploring its readers to “think ahead for the 1980s” is a wonderful reminder that future has a curious way of getting cheaper and cheaper.

My quick back-of-the-envelop calculation estimates that if your $29.99 32GB jump drive were priced at a level comparable to the late 1970’s it would today cost about $100,000. Another way to think of it is this: That 10MB which cost $5995 three decades ago can today be purchased for less than $2.

This historical footnote is important because many people mistakenly believe that 3D printers, robots, solar cells, fuel cells, a college education and scores of other technologies and products will always remain expensive and out of the reach of ordinary people.

This isn’t true.

For example, the price of a 3D printer could drop to next to nothing as soon as a 3D printer can print all of the parts necessary to make a copy of itself. Similarly, an Ivy League education might soon be able for free due to the acceleration and growing popularity of Massive Open Online Courses (MOOCs).
