Computers don’t mind if I must make effort to communicate with them or if it is easy to communicate with them. They don’t care if I put the numbers of instruction byte sequences in a file and feed it to them to run, or if a very high level language generated the instructions. The computers don’t care. We humans care about the effort we pay. Often people, especially computer engineers, focus on the machines. They think, “By doing this, the machine will run faster. By doing this, the machine will run more effectively. By doing this, the machine will something something something.” They are focusing on machines. But in fact we need to focus on humans, on how humans care about doing programming or operating the application of the machines. We are the masters. They are the slaves. – Yukihiro Matsumoto
