It's very good. It takes a couple of reads to see all the interconnections.

Here's another choice passage:

"Well, it was a kind of back - to - front program. It's funny how many of the best ideas are just an old idea back - to - front. You see there have already been several programs written that help you to arrive at decisions by properly ordering and analysing all the relevant facts so that they then point naturally towards the right decision. The drawback with these is that the decision which all the properly ordered and analysed facts point to is not necessarily the one you want."
"Yeeeess..." said Reg's voice from the kitchen.
"Well, Gordon's great insight was to design a program which allowed you to specify in advance what decision you wished it to reach, and only then to give it all the facts. The program's task, which it was able to accomplish with consummate ease, was simply to construct a plausible series of logical - sounding steps to connect the premises with the conclusion.
"And I have to say that it worked brilliantly. Gordon was able to buy himself a Porsche almost immediately despite being completely broke and a hopeless driver. Even his bank manager was unable to find fault with his reasoning. Even when Gordon wrote it off three weeks later."
"Heavens. And did the program sell very well?"
"No. We never sold a single copy."
"You astonish me. It sounds like a real winner to me."
"It was," said Richard hesitantly. "The entire project was bought up, lock, stock and barrel, by the Pentagon. The deal put WayForward on a very sound financial foundation. Its moral foundation, on the other hand, is not something I would want to trust my weight to. I've recently been analysing a lot of the arguments put forward in favour of the Star Wars project, and if you know what you're looking for, the pattern of the algorithms is very clear.
"So much so, in fact, that looking at Pentagon policies over the last couple of years I think I can be fairly sure that the US Navy is using version 2.00 of the program, while the Air Force for some reason only has the beta - test version of 1.5. Odd, that."

Highly recommend reading it!
