"Okay if you say so, Mike. But if needs a fast program, will still have to phone you." Greatest shortcoming of computers isn’t computer shortcoming at all but fact that a human takes a long time, maybe hours, to set up a program that a computer solves in milliseconds. One best quality of Mike was that he could program himself. Fast. Just explain problem, let him program. Samewise and equally, he could program "idiot son" enormously faster than human could.
