Running system agent software was a little like having a virtual personal assistant—one that also functioned as a voice-activated interface with your computer. System agent software was highly configurable, with hundreds of preprogrammed personalities to choose from. I’d programmed mine to look, sound, and behave like Max Headroom, the (ostensibly) computer-generated star of a late-’80s talk show, a groundbreaking cyberpunk TV series, and a slew of Coke commercials.
