As technology evolves, we may reach a point where its true worth cant be measured in how much work we can get out of it. Maybe someday, robots and the people who make them will be judged by how much fun we can have with them. Its speculation at this point, but not for lack of trying; theres at least one out there more than willing to play along.
Tokyos Ishikawa Watanabe Laboratory is the home of Janken. The robot was designed with one purpose above all others in mind: playing rock-paper-scissors with anyone who dares to challenge it. As expected, its very good at what it does; not only does it boast a perfect win record, but its only gotten better over the years. At its slowest when it was first unveiled in 2012 it had a twenty-millisecond delay after an opponent threw out his hand. Thats still only a minor delay, and one thats been completely erased thanks to its latest iteration.
The key to Jankens streak is its vision, not its hand. Thanks to its high-speed tracking systems, it can effectively act and react three times faster than the average human. Unfortunately, that takes the fun out of any games with it, since defeat is virtually guaranteed; still, maybe Janken can teach future robots how to put those high-speed parts to good use.
