Many people are also unaware that json is way, way, way faster than Python pickles, and human-editing-friendly. Not that you'd use it for neural net weights, but I see people use Python pickles all the time for things that json would have worked perfectly well.

Are you sure json is faster than pickle in recent python versions? That's not intuitive to me and search result blurbs seem to indicate the opposite.
