From the beginning, HUBO was better than the other robots at performing the tasks. ( ① ) It was able to drive a vehicle fast and when it encountered a barrier, it was able to turn the vehicle smoothly to avoid it. ( ② ) Next, it was able to get out of the car in less than four minutes and, once out of the vehicle, got on its knees and sped away. ( ③ ) As the series of eight tasks became progressively more difficult, HUBO's performance on the tasks reflected the growing difficulty. ( ④ ) On the fifth task, for which it had to use a drill to cut through a wall, HUBO failed on its first attempt. ( ⑤ ) Generally speaking, it was difficult for a robot to hold a drill in the right position and simultaneously press an on/off button. ( ⑥ ) The task that took the longest time for HUBO was the sixth one, pulling a plug out of a wall socket and putting it back into another. ( ⑦ ) It takes a human less than 10 seconds to perform the task, but it took HUBO 13 minutes and 30 seconds.

Herbert Simon won his Nobel Prize for recognizing our limitations in information, time, and cognitive capacity. ( ① ) As we lack the resources to compute answers independently, we distribute the computation across the population and solve the answer slowly, generation by generation. ( ② ) You don't need to understand how your computer or toilet works; you just need to be able to use the interface and flush. ( ③ ) All that needs to be transmitted is which button to push ─ essentially how to interact with technologies rather than how they work. ( ④ ) And so instead of holding more information than we have mental capacity for and indeed need to know, we could dedicate our large brains to a small piece of a giant calculation. ( ⑤ ) We understand things well enough to benefit from them, but all the while we are making small calculations that contribute to a larger whole. ( ⑥ ) We are just doing our part in a larger computation for our societies' collective brains.
