Well, yes, that’s entirely true. You’d have to extend it for other purposes because unless you have documents and other text which CAN be organized in a list fashion nicely, it won’t work. You can also incorporate it into programming languages as either a data structure, or the premise on which the language is built, such as Lisp, where everything is basically a list or an atom (lists and entries in ELF).

As he also says, ”[e]volutionary file structures, and the ELF in particular, are designed
to be changed piecemeal by a human individual.” That’s the kind of limitation I am talking about. He didn’t seem to see past the initial ideas of computers, and with that statement makes it seem as though they would be suited to store data, but not manipulate it or process it. I don’t think anybody will deny that when you use a computer to do something, you tell the computer what you want to do (mouse clicks, keyboard, etc) and it does it (prints your document, open a web page). There is no human manipulation of data on the disks directly.
