Neil Gershenfeld from MIT speaking at the World Science Festival. He was plugged as a pioneer of 3D printing (and maybe he is?) But he spent most of the talk criticising 3D printing and other technologies common in the maker movement, like Arduino.
He calls them “bad standards at a good time”. So they garner interest and encourage innovation, but tend to blinker the hobbyists who become enamoured.
The main takeaway from the talk was: don’t Do It Yourself; instead, Do It Together. Learn and share together. Mentor and be mentored. That way, the best methods and technologies are more likely to be adopted, and makers won’t repeat mistakes that we’re already solved by others.
