Ward's Laws #1952

Back in the 70's scientists created the mood ring.  A wearable device that could interpret if a person was happy or sad.  More than 40 years later what has science brought us?  Mind-bending mental powers, or cyber enhanced psychic abilities?  No, they're still riding on the laurels of the mood ring.  Come on scientists.  You've got computers and robots, what did we have back then?  Slide rules and the Dewey Decimal system.  Even NASA went back to the rocket.  Just watch a few episodes of Star Trek so you can rip-off more ideas from the past you lazy bums.
