There's some super-interesting recent empirical work from MS research that makes this perspective less likely to be a useful one. In short, the behavior of neural networks in a few regimes makes this interpretation of them less likely, specifically: ensembling the same network trained multiple times separately improves results compared to training multiple networks concurrently, knowledge distillation works, and self-distillation works. The blog post[1] has a good intuitive explanation of the matter and a link to the paper.

To add on: Zeyuan Allen-Zhu and Yuanzhi Li had a great theoretical paper earlier last year proving a fundamental discrepancy between the concept classes learnable by kernel methods and deep learning models.
