I was always moved to frustration every time I was reminded of the 'time capsule' they sent to space as a stab in the dark at contacting extra terrestrials, fitted with a golden record of earth sounds and no player. No instructions. Just a record. Sure, it's possible that sentient beings are going to understand enough about a grooved golden disc to build a damn turntable, but is it reasonable? I guess it still moves me to frustration. |
