Google hit the jackpot with their acquisition of YouTube and it's now paying dividend. YouTube is the largest single source of data and traffic on the Internet, and it's still growing fast. I think this data will prove incredibly important to robotics as well. It's a shame they sold Boston Dynamics in one of their dumbest ever moves because of bad PR.
Why should YouTube be here at the advantage? Every competitor also has access to these videos(?)
I mean, you could limit yourself to the most popular or most interesting 100 million, but that's still an enormous amount of data to download.
