The important part is of course the legal questions it raises.

I love this idea! Also, I have to add something: If the URL-shortner uses 302 to redirect to the full URL, the content part behind the anchor/hash will not be sent to the server. It will still available to the JavaScript returned from the server that is run in the browser. So the server will not know about the content. (This feature is already used by e.g. OAuth2) In addition, instead of accessing a remote server, the URL could point to localhost, and the user could run the "content unpacking" webserver locally (and maybe automatically prevent any unwanted cross-site requests, since this is the default behaviour of the browser)

Firstly what kind of IT workers are we discussing? IT support, web designers, network administrators, software developers, architects, computer science professors? There's a difference. Anyway. I personally got my first tastes of programming as a kid about thirty years ago. I have a bachelor's degree in computer science and have been working as a developer and also as a development manager for many years. Currently I'm working full time and at the same time I'm studying part time for my master's degree. And I'm actually quite impressed by the students I've met at the university. They don't have much real work experience in development, but they most certainly are very intelligent and talented. Some will go on to take a PhD, some will start working in the business after finishing their master's degree. No matter what direction they decide to head towards, I'm 100% confident that the next generation will be excellent at diagnosing problems, developing solutions, implementing them, and everything else that is needed. I'm not at all worried for the future of computer science anymore.

The experiment can hardly be called real world.

I think the next big technology revolution will be the use of molecular biotechnology.
