>> This leads me to wonder: what abstractions are we missing today that will be obvious to future generations? That's a very nice question. But I tend to see it like this : if you'd know, it'd mean that somehow you predicted the future. I'd say that abstractions are built everytime but only the good ones survive. So the only way to answer your question is to wait 50 years. Then we'll know what are those missing abstractions. But the simple act of asking the question already opens the way to a critic of current abstractions, which will lead to new ones and maybe, one of the future :-) Are there public places where such things are discussed ? I mean, places where you don't need to be inside a university to actually participate.
