It’s been so many years since I read Foucault’s Pendulum that I don’t recall the computer, or its program. But my memory is that the confabulation they created was real — by accident, yet it was.

(The article is likely correct - it was not real but was believed to be so by people who wanted it to be. Which I in turn misremember as stumbling on something real that is confirmed bu those same conspiracy theorists.)

Perhaps I misinterpreted what I read. Yet if so that would be a surprising twist on the point of this article.
