"Servo-mechanisms are the future."
- What my great-uncle said to my dad in the 60s or 70s.
My great-uncle told me this over the phone last week, and I didn't even know what servo-mechanisms were. (It's a mechanical device that has built-in error correction systems, using negative feedback.) In hindsight, he lamented that he didn't see the oncoming growth of software. I'm amazed and proud that my great-uncle, at age 92, still reflects on technology and innovation, and evaluates the accuracy of predictions he made 30+ years ago. Cool.
