Software Engineering Too Difficult

“Software engineering is the part of computer science which is too difficult for the computer scientist.”

Useful Software Systems

“We recognize that a practical problem of considerable difficulty and importance has arisen: The successful design, production and maintenance of useful software systems. The importance is obvious and the more so since we see only greater growth in demands and requirements in the future. The consequences of poor performance, poor design, instability and mismatching of promise and performance are not going to be limited to the computing fraternity, or even their nearest neighbors, but will affect considerable sections of our society whose ability to forgive is inversely proportional to their ignorance of the difficulties we face. The source of difficulty is distributed through the whole problem, easy to identify, and yet its cure is hard to pinpoint so that systematic improvement can be gotten.”

Computing Fun

“I think that it's extraordinarily important that we in computer science keep fun in computing. When it started out, it was an awful lot of fun. Of course, the paying customers got shafted every now and then, and after a while we began to take their complaints seriously. We began to feel as if we really were responsible for the successful, error-free perfect use of these machines. I don't think we are. I think we're responsible for stretching them, setting them off in new directions, and keeping fun in the house. I hope the field of computer science never loses its sense of fun. Above all, I hope we don't become missionaries. Don't feel as if you're Bible salesmen. The world has too many of those already. What you know about computing other people will learn. Don't feel as if the key to successful computing is only in your hands. What's in your hands, I think and hope, is intelligence: the ability to see the machine as more than when you were first led up to it, that you can make it more.”

Egoless Programming and John von Neumann

“Programming groups who have conquered the ego problem do exist and have existed from the earliest days of computing. John von Neumann himself was perhaps the first programmer to recognize his inadequacies with respect to examination of his own work. Those who knew him have said that he was constantly asserting what a lousy programmer he was, and that he incessantly pushed his programs on other people to read for errors and clumsiness. Yet the common image today of von Neumann is of the unparalleled computing genius — flawless in his every action. And indeed, there can be no doubt of von Neumann's genius. His very ability to realize his human limitations put him head and shoulders above the average programmer today. Average people can be trained to accept their humanity — their inability to function like a machine — and to value it and work with others so as to keep it under the kind of control needed if programming is to be successful.”

Quantum Computing

“The basic idea of quantum computing... is to do different computations in parallel along different possible threads of history. But the key issue is then how to corral those threads of history together to figure out a definite answer for the computation... The preliminary indication is that at least at a formal level, quantum computers aren’t going to come out ahead.”
