The algorithm flaw is it only works for as long as the average human poo. So quite literally, these algorithms are poo algorithms, designed to hold our attention for our median bathroom duration. Poo algorithms are relatively powerless–they have no sway over the human mental condition.
In fact, we should marvel at the unifying element of the poo algorithm, an entire species locked in on a common, unifying experience. The UN could open up sessions with “did you see this while on the shitter?” and we would be better for it.
