I had the same issue. I have a rough idea (I think) of what Polar is trying to do -- but I'm not entirely sure. I'm also not sure how this would be "rebooting the internet", or what the overall benefit to the internet actually is. I may have missed it (that's likely), but I didn't see where that was explained.

It may be that the video explained it, but I'm not be in a situation where I can watch it right now.

EDIT: After reading the bulk of the other comments here, I am relieved that I'm not the only confused one. I thought I was just being stupid. I often am.
