The question is not so much whether this is true—we can certainly represent any data as points on a manifold. Rather, it’s the extent to which this point of view is useful. In my experience, it’s not the most powerful perspective.
In short, direct manifold learning is not really tractable as an algorithmic approach. The most powerful set of tools and theoretical basis for AI has sprung from statistical optimization theory (SGD, information-theoretical loss minimization, etc.). The fact that data is on a manifold is a tautological footnote to this approach.
