I don't know. I think what we all do, we know how to do it without a computer. Computer just automate stuff for us. It's a very practical saying because it forces you to ask the right question about the problem you're trying to solve. (We all know how to do AirBNB by hand, or Uber by hand, but the mobile app is hyper efficient w/ GPS & 4G, that's all).
