I am stoked to see "The Adolescence of P-1" on the list. (In my more paranoid moments I have suspected it was autobiographical.)
I recently (finally) read "Gateway" and was surprised to discover that it's an AI story. The main character is (arguably) "Sigfrid" the AI psychoanalyst. "Gateway" is always presented as an alien-archeology adventure, but the Heechee are just a plot device, as is most of the plot. The actual story is about the AI trying to treat the messed-up human, but you wouldn't know it from e.g. the Wikipedia entry (warning, spoilers): https://en.wikipedia.org/wiki/Gateway_(novel)

Should mention Larry Niven's magic stories.
Also, Vernor Vinge's "True Names".
