It doesn’t matter if you disagree (BTW I don’t know what you disagree with specifically, and I did not mention the Universal Approximation Theorem. It seems like you’re making some assumptions.) A polynomial spline is still a subset of a neural network, so if you’re right, all you’re demonstrating is that splines also suck at solving the same problems that neural networks solve. The discrepancy between the two here, again, has nothing to do with networks and everything to do with your contrived example.
