"Today, we have Fitbit, a tiny wearable computer that instantly analyzes your physical activity from inside a band slipped over your wrist. But in 1959, a state-of-the-art physical activity tracker was a little different.
It weighed about 2,000 pounds (4,000 with the power supply). It asked you to input all data by hand (through a punch card reader). And it needed several hours to spit out the results (if you were lucky)."
And just as importantly, if we've gone this far in 65-odd years, where will we be in another 65?
