Perhaps this is because I'm from the generation that grew up watching 'The Jetsons' on TV, but I really thought we would be much more advanced in the areas of transportation and medicine.

I took this 'how to build computers' course basically because I'm sick and tired of getting ripped off by cheesy computer companies. Software baffles me. I like hardware. I used to change my own oil, and now I want to build my own computer so I can have what I want.

I used to think that, by the 21st century, cars would run on electricity rather than gasoline and would have guidance systems so that they actually drove themselves. Specially equipped roadways would transmit instructions to the cars, telling them where to go and how fast. I figured this would be in the lines painted on the roads.

Most people who are on the inside of a technology have no idea what it's like to look at from an end user's point of view. This is why they have focus groups. I'm really familiar with this because I worked 10 years for Hallmark Cards in the U.S.
