But I'm afraid it won't happen for awhile, for several reasons:
1. The technology just isn't there yet. MIT's entire lecture series is not online, far from it. Many of the OCW courses have only notes, no video, and the ones that have video often lack resolution to be able to read the notes on the board. Also, has anyone ever used Blackboard? It's horrible.
2. Not everyone has the tenacity to sit through four years of college classes and really learn something. Even fewer have the dedication to do it on their own, remotely, with no human interaction other than a webcam to guide them.
3. Schools such as MIT serve as a filter and a credibility indicator. They have great professors, of course, but anyone can obtain the raw knowledge they teach. What's harder to obtain on your own is the stamp of approval that you've . PG commented on Dropbox's YC application that was posted on here with his thought process. One of the first items was: "MIT...must be pretty smart." That's the power of a credibility indicator at work.
4. The people that are needed to make this happen are 1) parents, 2) government (for incentives), 3) existing institutions of higher learning, 4) employers (to hire these graduates). All of these groups are likely to have degrees that are granted using the current model, and thus none are likely to want to undermine their own education choices. What's the incentive for them to break with status quo?
5. School isn't just about what you learn...the best schools serve as a kind of bridging ground between childhood and adulthood. Perhaps there are better ways to accomplish this, but some kind of "GED for higher education" hardly seems to be a good solution. I'd rather hire employees who are smart and dedicated than knowledgeable. Most of what they need to know can be taught, but character and raw intelligence can't be, or at least not easily. Getting good enough grades in high school to get into a great school and then doing well in that school indicate both mental aptitude and the perseverance that I want in people who work for me.
These are off the top of my head...I'm sure there are more.
