To this day, I am creeped out by how often I use HALs (Hardware Abstraction Layers). Was that acronym in common use at the time that the book was written? How about the movie? Which way does that causation go, if it exists at all? Sorry for the off-topic question, but it really does haunt me. Modern HALs are like rat nests, and I imagine it was worse in decades past. So it must be a pun...right?
