I want a “thing” installed in my fingertip that allows me to see the meaning of any word I don’t know in any language, just by touching it on the surface of a page or screen or some other viewer. I also want it to show me the full cone of that word’s scope, its etymology, and the history of its usages. I don’t mean in the sense of a bunch of links to follow, like hypertext, but in the sense of immediate full cognitive awareness.
