I generally agree with this article, and I am, and continue to aspire to be, a strong generalist data scientist. However, I do still enjoy/need to have 1 or 2 really really strong quants/statistician types on my team, since they are able to solve certain problems at a level of depth I can't reach. However, if they aren't supported by generalists, they also struggle to make impact.
Yes, indeed, the main issue TFA missed out on is comparative advantage.
Theoretically speaking...it's much more efficient to have the specialists doing what they do best instead of trying to learn how to optimize SQL queries or whatever.
