“Inventing is the mixing of brains and materials. The more brains you use, the less materials you need.”
--- Charles F. Kettering, U.S. scientist and engineer (1876-1958)
I like this quote because it says a lot about what we are capable of if we only let ourselves. For example, learning to compute in our heads without calculators or learning to play without having to turn on a video game.
Inventing has a lot to do with thinking about our world and what will be useful, not just remove tasks to free ourselves from actually doing the work. Vacuuming burns calories, but if we let robots do all the work, we won’t remember how to do the most basic of needs.
