ABSTRACT
Twenty-seven years is an awfully long time. Twenty-seven years ago one of us was still in graduate school (AC), one of us was just out of high school (JL), and one of us had just had his bar mitzvah (JN). The Soviet Union was still considered the United States’ chief nemesis, and Ronald Reagan was president of the United States. Twenty-seven years ago IBM had just released its XT personal computer, which came with a whopping 128 kB of memory and a floppy disk drive to boot. The World Wide Web was not yet invented, and cell phones were in their infancy. There was no Facebook. There was no Farmtown. There was no Wii.
