They tell you if your food sucks
Chinese web services giant Baidu is developing chopsticks that go all Dr. Spock on your food, giving you science-y information about how good or horribly bad it is without sugarcoating facts like you secretly wish they would. The project actually started out as a web prank, but now it's become very, very real.
By flashing blue or red, the sticks let you know if the oil used in your food is of guiltlessly edible quality -- a ubiquitous concern in China, where an estimated one in 10 meals served uses gutter oil. The utensils will also be able to gauge PH levels, temperature and caloric information, and send nutritional data to phones via an app.
If the technology takes off, you might soon be forced to reckon with the fact that you ingest enough salt to cure a pound of jerky every week, and that in general you will, without hesitation, eat something you know with certainty is downright toxic, if it smells and looks good enough.
