Sounds spiffy. Also, I must find time to learn Julia.
One problem with these 'out of a box' cookbook systems is that you only know approximately what you are doing. If it works, that may be fine, but for statistical systems the outcome depends heavily on the formulation, is strongly influence by random or irrational correlations and is more art than science. If you remove the element of experience that animates the "art", you get nonsense. Big box programming tools can make it hard to know what correlations are being established, and this is true with even simple neural networks. By the time they have many layers and filters in them, all hope is fled. You buy the result or you don't: simple as that.
