Things that stood out to me was the maker mindset was so prevalent and competitve that it had filtered down to the buyers. So someone cobbles together some new widget for their phone and starts to sell it. Other people see it selling a nd copy it, but they make modifications. Shoppers see it for the first time and decide they want one with a purple strap, so they shop around until they find it or find someone who will make it that way.

This is where the hoverboard fad bubbled up but also how and why it "flamed" out. I think it's a fascinating testbed for technology and creativity and economics.
