I'm listening to a very old Arthur C. Clark story, Rescue Party, ca 1946. I've found that classic sf tends to translate beautifully to audiobook format, and this one  is no exception. It's set in a world where science has advanced to the point where huge mountain tops can be casually sheared off to make a flat place for a gigantic observatory, but computers are still the size of small houses. Cities have been abandoned for centuries because of a fantastic new technology making it possible for people to live wherever they want. This world-changing technology was, of course.... helicopters!

Just before this, I re-read the remarkable Ware Tetralogy by Rudy Rucker (Software/Wetware/Freeware/Realware). These four books were written over a period of about 20 years: 1980-2000. The last three feel pretty modern, but the first one is still firmly rooted in the TransistorPunk era. In 1980 even Rucker's unfettered hallucinogenic imagination could not encompass the idea of a self-aware robot with a brain smaller than the size of a Mr. Frostee truck. By the 2nd book (1988), Rucker has realized how ridiculous this is and brutally dispatches all the mainframe-size AI's in one night with an infestation of "chipmold," an organism that quickly initiates the first of several Transhuman Singularities that power the rest of the series.

So there you have it - empirical evidence of where the dividing line lies between current science fiction (that still imagines a future completely unknown to us) and unintentional alternate-world TransistorPunk.
