The animations are really neat but I was thinking the same thing. It's science porn with emphasis on porn. But I don't think they're meant to be educational - "just" impressive.
But I'd imagine that if a society were starting over there would still be a lot to be learned, even with whatever guides were left behind. These animations could serve as a starting point for engineers to work from, discovering problems and solutions along the way. As far as sheer information density goes, I think these get a large amount done even if there is much left out.
