|the true form of the university has quietly vanished and reappeared elsewhere, I guess this would be it. Curious, where do you think it has 'reappeared'?
Yes, I think the TED talks are a part of what I'm discussing. Though their format is still primarily lecture based, and never (to my knowledge) dialectic or interactive, the diversity of subject matter, and the lack of institutional impediments seems to make it exponentially more useful to the cross-pollination of ideas and the organic development of a line of inquiry, rather than top-down knowledge drops. Thanks for reminding me, I reall need to check out the Khan institute. And coursera? News to me. Thanks!
I think it can be found anywhere the insatiably, omnivorously curious can be found together, indulging and sharpening each other's inquiries. It's kind of a secret society, not secretive, but difficult to locate nonetheless. Finding one participant usually leads to finding more, though. I think we've got a good strain of it thriving on this site, for example.
I think TED is fascinating, but I don't think it's a replacement for a college education. I can't really speak about the other two because I have only heard of them, I don't have any first hand experience. I hear what you're saying, I think it would be great, but I'm just not convinced we are quite there yet. Thanks for the links, I'll have to look it to them over summer break.
I've taken quite a few Coursera courses. The higher-level CS and otherwise technical courses are mostly great, introductory courses are awful, and the humanities courses can be fun but aren't really a replacement for actual classes. It's a fine way to learn new topics in a field you're already pretty familiar with, but I don't think it could replace undergraduate programs for getting people to that point. That might sound more negative than I mean it to; I love Coursera, I think it's a great project, I just think it really only shines in the graduate-level classes for students that have already been through a traditional university, as an alternative to just diving into an unfamiliar corner of the literature.
TED is definitely more focused on breadth and variety of subject matter, as cW mentioned above, so in the respect of "higher-level education," it may not replace traditional colleges. Khan, however, offers multiple lectures of increasing difficulty on an increasingly wide range of topics, from Basic Addition to Differential Calculus to the art of the Baroque period, along with exercises for some topics. It's certainly lacking in some departments (notably, there are no Writing, Philosophy, or Foreign Language classes which are so prevalent in traditional institutions) and the experience is completely void of any personal and social interaction, but it's certainly a good model for things to come, as you said.
