Top Down Bottom Up

“In the designs I have been involved in, and which have not involved too many people, I have not been able to identify whether these have been ‘top-down’ or ‘bottom-up’. They seem to me to be more like frame stressing,”

Global Alignment

“It is impossible for physicists to identify global alignments... For although physicists can test individual events in the laboratory and verify that, when taken in isolation, the events are random, they wouldn’t be able to discern a global pattern within the complexity of the physical world at large; there are just too many ‘dice’ to keep track of under controlled laboratory conditions.”

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.”

Computational Irreducibility

“I’ve increasingly come to view the whole fundamental story of science as being about the interplay between computational irreducibility and computational reducibility. The computational nature of things inevitably leads to computational irreducibility. But there are slices of computational reducibility that inevitably exist on top of this irreducibility that are what make it possible for us — as computationally bounded entities — to identify meaningful scientific laws and to do science.”

Simple Purpose

“Whenever there’s computational irreducibility we can think of it as exerting a powerful force towards unpredictability and randomness... So for a system to achieve an overall “computationally simple purpose” this computational irreducibility must in some sense be tamed, or at least contained. And in fact it’s an inevitable feature of computational irreducibility that within it there must be “pockets of computational reducibility” where simpler behavior occurs. And at some level the way computationally simple purposes must be achieved is by tapping into those pockets of reducibility. When there’s computational irreducibility it means that there’s no simple narrative one can expect to give of how a system behaves, and no overall “mechanism” one can expect to identify for it. But one can think of pockets of computational reducibility as corresponding to at least small-scale “identifiable mechanisms”... When there’s a “simple overall purpose” being achieved these mechanisms tend to become more manifest.”
