Today, thanks to low-cost computers, the Internet and platforms such as YouTube, millions of people are making their own music videos.

Tomorrow, millions will be building their own products thanks to low-cost 3D printers and peer-to-peer sharing platforms.
The lesson for the future: Yesterday’s underground is tomorrow’s mainstream. (Lesson #2: See how the Homebrew Computer Club of the mid-1970’s foreshadowed today’s personal computer industry.)
