Think back on the computer you used as a kid. Was it a Macintosh? A Gateway 2000? A $3,000 Dell? The color interface was mind-blowing. The dial-up Internet was speedy. Microsoft BOB wasn't even widely considered retarded. The computer was magic.
Yeah, it doesn't work now. It's obsolete. You can't even turn it on. Even if it's not currently buried in a Hudson landfill, it probably hasn't worked for years. This is both the blessing and curse of technology, a sad observation that none other than Steve Jobs made while promoting his line of NeXt computers in 1994. Moore's Law tells us that technology is speeding at an exponential pace—that each year, we double the capabilities held by our machines. The computer moved from the office to the home in the '80s. Now it's in our pockets. In a decade or two, it'll probably be in our heads.
So, like Jobs says, think of each innovation as a layer of sediment in a technological mountain. In other words, don't get too attached to the shiny new toy you currently type on. You'll be laughing about it in 20 years.
