Reminds me of playing life on a minicomputer at my dads work in 1970. It's hard to grasp the feeling of seeing that when nothing like it exists elsewhere. Almost everything mechanical in 1970 was a purely mechanical device without a shred of agency. At the heart computers can represent and transform complex structured data iteratively. That was new new 50 years ago.
