But which side do you think the econometricians should be on?

Excellent reply from Franck Nadaud. Me, as an outsider of this discussion (I have a degree in Operations Research, but I work as Software Tester), I have a neutral position, or more like a grey color in the white vs black discussion (pick one color for Statistics ;) ). I would say the Econometricians would be more on the grey side but with a bias to the Statistics color :). We can see the advantages of Data Science, in processing big samples of data and extracting patterns that a human would not be able to see (or too live long enough to find them). (I am mostly thinking on DNA, medical/medication research). I am not advocating for either side, there are advantages in all these (three sciences), it is a matter of selecting the adequate tool to solve the problem at hand. Currently, there is this feeling, that everyone can be a Data scientist, by just applying a bunch of algorithms and draw conclusions from them. I think that a good background in Statistics is essential to be a Data scientist (as it is for an Econometrician). When I think about this Computer Science vs Mathematical reasoning, I always think about the Four Color Theorem <https://en.wikipedia.org/wiki/Four_color_theorem>which was possible to proof with a computer executing, a mathematical model. These days we need to stop COVIR-9 spreading in the world, hope scientists with whatever science, tools, or techniques, they find good solutions (and political powers listen to them). Thank you all, for keeping doing science (and teaching)!
