How did Stanislaw Lem imagine advanced computer intelligence?

…GOLEM’s behavior is unpredictable.  Sometimes it converses courteously with people, whereas on other occasions any attempt at contact misfires.  GOLEM sometimes cracks jokes, too, though its sense of humor is fundamentally different from man’s.  Much depends on its interlocutors.  In exceptional casese GOLEM will show a certain interest in people who are talented in a particular way; it is intrigued, so to speak, not by mathematical aptitude — not even the greatest — but rather by interdisciplinary forms of talent; on several occasions it has predicted with uncanny accuracy achievements by young, as yet unknown, scientists in a field which it has it self indicated.  (After a brief exchange it informed T. Vroedel, age twenty-two and then only a doctoral candidate, “You will become a computer,” which was supposed to mean, more o less, “You will become somebody.”)

That is from Lem’s Imaginary Magnitude, an extraordinary book in parts, most of all see his Golem IV section on how n AGI (our term, not his) is likely to behave.
