@MrsPramm - I read a book once where they invented a kind of internet that could beam directly into people's heads and was available everywhere in the world, all the time. It seemed like the most crazy, outlandish science fiction when I read it, but honestly I don't think we're that far away from the reality now, at least insofar as the universal access goes.
When you have free internet hotspots everywhere for public access and the devices you can use to get onto them are extremely cheap, you've basically given everyone the keys to a huge amount of knowledge. There are huge libraries of free books online, articles on every subject known to humankind, music and video and so on and so forth. People can do a free course from Yale in their spare time at a coffee shop for the price of a cheap tablet.
It's an amazing world we live in.
