Dr. Amy Smith is a professor in the Department of Mechanical Engineering at MIT, where she runs the Development Lab, or D-Lab, a lab organized around simple and cheap engineering solutions for the developing world.

Among the rules of thumb she offers for building in that environment is this:

“If you want something to be 10 times cheaper, take out 90% of the materials.”
Making media is like that now except, for “materials”, substitute “labor.”
