Remind me of the story about Star Trek scripts, where the screenwriters used to leave blanks labeled (TECH) to be filled in with largely meaningless technobabble like "multi-phasic temporal convergence." You could totally generate that, these days a computer could even infer what kind of technobabble to insert from the context.
