The little robot "Moore" has been climbing Everest since the 60s. It started out slow, and has been going faster and faster as time goes on. From 1960 to 1996 it had managed to climb 1/10th of one inch up the slope. In 2007 it made it up the first foot. Today is it 7 whole feet up the mountain. The view is looking impressive.
In 2017 we'll be 113 feet up. In 2020 453 feet up. In 2029 we'll be 29,000 feet up, at the summit.
