The human primate has a powerful ability to learn through observation of other human primates. Scientists are beginning to understand the neurobiological basis of that ability. That neurobiology drives, in part, Crowd Accelerated Innovation.
Currently, the internet is a massive catalyst for this process. A climber no longer has to be present to watch someone else climb. He or she can watch a video of a climb and learn. He or she still has to work out the particulars, but the learning process for that climb is accelerated. The open sharing of climbing videos (of any quality) will help push climbing forward.
