It would be majestic if it weren't so absurd. Who's written anything worthy of that treatment? I think this is why literate programming interests me. Almost none of the code written today is worthy of being a real cultural artifact, or even a family heirloom.
I agree it would be fun, and I probably spend too much time worrying about future archeologists, I just think it would be nice if we had some code that was worthy of the honor. Practicality seems to demand that code be functional first and beautiful a very distant second, despite all the talking and blogging to the contrary.
