[Talk of the week]( [Simone Giertz: Why you should make useless things](
11:57 minutes · Filmed Apr 2018 · Posted May 2018 · TED2018
In this joyful, heartfelt talk featuring demos of her wonderfully wacky creations, Simone Giertz shares her craft: making useless robots. Her inventions -- designed to chop vegetables, cut hair, apply lipstick and more -- rarely (if ever) succeed, and that's the point. "The true beauty of making useless things [is] this acknowledgment that you don't always know what the best answer is," Giertz says. "It turns off that voice in your head that tells you that you know exactly how the world works. Maybe a toothbrush helmet isn't the answer, but at least you're asking the question."
