Their applications are tabular data (for which MLPs have never been the method of choice) and MNIST (which I could classify at 85% with a rusty nail), so it's not super impressive.
NNs and the associated toolkit shine with structured high-dimensional data where CNNs, RNNs, or modern shenanigans like Transformer networks excel. I sincerely doubt that these networks turn out to be reducible to polynomial regression in any practically useful sense of the notion. But who knows.
