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.
