This paper is an attempt to imagine what an OS would look like and how it would work if looking for a word 'foo' in something and deleting/closing/stopping this something, -- be it a paragraph of text, a network connection, a subscribed newsgroup, a process -- would all require roughly the same sequence of mouse clicks or keystrokes, and would be understood and interpreted in the same spirit by the operating system.

When great thinkers think about problems, they start to see patterns. They look at the problem of people sending each other word-processor files, and then they look at the problem of people sending each other spreadsheets, and they realize that there’s a general pattern: sending files. That’s one level of abstraction already. Then they go up one more level: people send files, but web browsers also “_send_” requests for web pages. And when you think about it, calling a method on an object is like sending a message to an object! It’s the same thing again! Those are all sending operations, so our clever thinker invents a new, higher, broader abstraction called messaging, but now it’s getting really vague and nobody really knows what they’re talking about any more. Blah.

When you go too far up, abstraction-wise, you run out of oxygen. Sometimes smart thinkers just don’t know when to stop, and they create these absurd, all-encompassing, high-level pictures of the universe that are all good and fine, but don’t actually mean anything at all.
