David Auerbach: My first computer was an Apple IIe with 128KB of RAM, no hard drive, and a 5¼ inch floppy drive. One of the top educational games back then was Rocky’s Boots, an inventive game that taught the basics of formal logic to kids. I loved it when I was 6. Two years later, I got Robot Odyssey, which promised to expand on Rocky’s Boots by extending the formal logic to actual programming. The game devastated me. My brain could not comprehend how to solve its puzzles. I finally finished it—13 years later, and not without some assistance.
