We are already having this problem over at Google. The algorithm that recommends you Youtube videos based on all available data on previous preferences is in the form of a neural network which has performed so many internal modifications that the programmers and engineers there don't know how it runs the algorithm anymore. They are still fully capable of controlling it, but learning the particulars of the algorithm exacts such a high price in terms of manpower dedicated to it that even Google doesn't have enough brains to fully vet it.

Now, I wonder if that'll happen to DTube....
