> And it fails for pretty much the same reason Marx's ideas failed

It should be noted that Marx's ideas didn't fail, insomuch as most of his work is a (debatable, but not non-sensical) description of capitalism and its problems.

Maybe you meant some of his predictions, or the future society implementations of other people calling themselves Marxists?

Agile, regrettably, mostly did fail to live up to its promises.
