'Soft robotics' is a revolutionary technology you'll wish you could un-see.
In the future, flexible actuators like these may very well impact every aspects of our lives. Allowing for machines with greater flexibility and durability, they could be used to create vastly improved search-and-rescue robots, medical equipment, and dildos.
Really, I don't know why they have to look so phallic. The robot in this video, produced by Okayama University and the Tokyo Institute of Technology, is just a demo model, so they could have made it look like anything. More importantly, anything else. It's also threatening that it looks like penises but it's called "soft." That kind of language makes me want to buy a sports car.
To be fair, it doesn't just look like a penis. If you squint just right, you can imagine it's some sort of horrible tube worm groping blindly for your face so it can start eating it. If that helps you.
