Phantom OS, the 21st Century OS?

jonr writes "Phantom OS doesn't have files. Well, there are no files in the sense that a developer opens a file handle, writes to it, and closes the file handle. From the user's perspective, things still look familiar — a desktop, directories, and file icons. But a file in Phantom is simply an object whose state is persisted. You don't have to explicitly open it. As long as your program has some kind of reference to that object, all you need to do is call methods on it, and the data is there as you would expect."

the idea's worked in practice before

IBM also took the approach of ditching files, and just having persistence of objects (which yes, presumably somewhere in the bowels of the OS got written to disk). It was efficient enough to run on 1980s hardware, so I don't see a reason it couldn't be done today.

From Wikipedia:

In most computers prior to the System/38, and most modern ones, data stored on disk was stored in separate logical files. When data was added to a file it was written in the sector dedicated to this, or if the sector was full, on a new sector somewhere else. In the case of the S/38, every piece of data was stored separately and could be put anywhere on the system. There was no such thing as a physically contiguous file on disk, and the operating system managed the storage and recall of all data elements.

The only real problem with this guy's concept is that he's effectively going to rewrite the concept of a Smalltalk Image in Java.

If you read his FAQ, every point can be answered by Smalltalk. (And could be 30 years ago).
Unfortunately I have a feeling he's never seen Smalltalk, so he's going to re-implement it poorly.
