To me it seems a lot like the question of whether general, computationally tractable methods of compression exist.
Provided you are allowed to assume that the expected inputs obey some vaguely-sensible version of Occam’s razor, I would say that the answer is just “yes, they do”.
Clearly, I do not understand how this data point should influence my estimate of the probablity that general, computationally tractable methods exist.
