Thanks for this interesting post.

@mathowl is very correct. In addition, those tools are good in interpolating, but who knows what they can do when it turns to extrapolating. This is to me one of the most important drawbacks (at least in the context of my own research field), together with the fact that sometimes, we do not even understand what is going on in the black box. In this way, other methods that are possibly less powerful could be preferable (as we have more control).
