Suppose you are right (not saying you are, but you do have a point there), still that mess of a jumbled heap of disorganized half-assed standards is the most important thing to have happened in recent memory, and is a 100% must learn/must teach technology.
Sure, the web is what will be remembered more than any of the other things you mentioned. But it achieved all that in spite of the technology, not because of. Just about everything about the Internet (right from TCP/IP itself) is of the level "does its job, successful because it got there first, could've been way better".
Now that I think of it, science == open-source.
As a scientist, I can't even begin to fathom how you're making that comparison.
