BitTorrent and Khan Academy To Distribute Education 139
drDugan writes "BitTorrent, Inc. announced this morning that they have launched a partnership with the Khan Academy to distribute open education videos. They launched with more than 2,000 videos, covering high school and college level curriculum, across science, math, history, finance and test prep. All of the videos are free to download and open licensed with Creative Commons."

I think the idea is to enable non-profit organizations to download the source videos, put them on CDs/DVDs or what have you, and then distribute them to parts of the world that don't have internet access. You have to remember that there are about 1.5 billion people with internet access, which means you're excluding more than 3/4 of the world's population when you only offer online streaming. It also gives you the ability to convert them to DVD video, which means you don't even need a computer to view them.

Human interaction? You're interacting with humans right now. The internet is filled with people who are intelligent and open to conversation (and vice versa, as in college).
