This is a solid list. It will be even better if juxtaposed with current efforts to solve each of these problems - every DS I know is addressing at least 2-3 of these with some pet tools in their own environment. For example, we use Panel and Holoviews to make data exploration much easier. I have a feeling the ecosystem would improve faster if we had an index of (partial) solutions aligned with this problem set. One category left out of the list: testing of data pipelines (c.f. great expectations).
