In the late 80s I was working at Rabbit Software in Malvern PA (they made IBM 3270 terminal emulator software). I used to car pool to work from Phila. with a brilliant woman who was a lot older than me, and had a solid lifetime of IBM mainframe experience. I was a Unix hacker with just a few years under my belt.

We realized very quickly that if there was one thing we couldn't talk to each other about, it was computers.

Back in 1984 George Lewis apparently did a stint at IRCAM, culminating in an electro-acoustic performance with three Apple IIe's connected by MIDI to three DX7s. I'd bet his conversations with the IRCAM directors were similarly limited!
