I don't know the answer to that historical question (shaky data point: though I know Brendan Eich is a bit of a capability convert, I believe that's relatively recent thing: last decade or so?). Regardless of the answer, I'd agree if you said that the world seems filled with people reinventing capability ideas not as effectively as they could, because they don't know that that's what they're doing and so are cut off from the ideas that have developed in the small cap community over the decades. This isn't really about files, though. Capability UI patterns are about composing all kinds of authority in a usable way. I'm sure we'd all agree that accessing files isn't the best or ultimate description of the interesting things that people do with computers now. This is an area that's waiting to be rediscovered by the rest of the world.
