I think the idea is that the kind of organization that would create the wayback machine in a world prior to the wayback machine is one which will also continue to push boundaries beyond that

I think that argument has a certain stasis to it, and kind of assumes that organisations maintain their energy and people (and those people are not changing!)… but there are realities where the initial push is by some people and then future maintenance is by others.

But I think the IA is a uniquely tough project because of how much the ground is shifting around them constantly. It’s not Wikipedia
