"While MOOCs are incorporating adaptive learning routines into their software, their ambitions for data mining go well beyond tutoring. Thrun says that we've only seen "the tip of the iceberg." What particularly excites him and other computer scientists about free online classes is that thanks to their unprecedented scale, they can generate the immense quantities of data required for effective machine learning. "

"Human brains will someday extend into the cloud, futurist and computer pioneer Ray Kurzweil predicted at the DEMO conference here on Tuesday. Moreover, he said, it will become possible to selectively erase pieces of our memories, while retaining some portions of them, to be able to learn new things no matter how old the person is." Of course, it's all about AI and augmented reality, leading right up to our having an augmented brain. Which, in a sense, we have for so long already - at least since we invented writing. But okay, in many ways we're re-inventing writing.  You'll find the video at Computerworld. 

Overcoming spinal cord injuries (I learned a lot about the spinal cord from the first segment, e.g. the systems that control walking are at the base of the spinal column, the brain has little to do with it), remote brain controlled mechanical hands, self-directed robots, and so on:

"n a recent Wall Street Journal interview about college costs and online learning, Stanford University President John Hennessy said, "What I told my colleagues is there's a tsunami coming. I can't tell you exactly how it's going to break, but my goal is to try to surf it, not to just stand there." "

Codeacademy is a start-up teaching people to code. It has tremendous succes. 

Will the evolution of the internet reduce or increase cognitive inequality? The answer may not be so straightforward.
