I think there is a wealth of fiction out there that features AI without robot bodies. The sequel to Ender's Game, Speaker for the Dead, comes to mind immediately (because I re-read it last week).
2001: A Space Odyssey, I Have No Mouth and I Must Scream, Neuromancer (I think, haven't read it in a while), I think some of of the short stories from Ray Bradbury and Ted Chiang, etc, etc
The series (basically everything in the https://en.wikipedia.org/wiki/Eight_Worlds) is pretty dated but Varley definitely managed to include some ahead-of-his-time ideas. I really liked Ophiuchi Hotline and Equinoctial
