Well, there is a net benefit of everybody being able to do more things instead of delegating: responsibility.

If I have to do my stuff, I can stop blaming others. This is good for me and for the others. Even if the information artist guy made better visualizations, the people at the lab could blame him for not doing them as they envisioned, and the guy himself could not put the best of his effort on doing things, because they weren't made directly for him, so the blame could would be probably justified.

But, well, it is better to step away from this world of giving responsibility to others and then blaming them, into a world in which everyone do their best and don't blame anyone. Even if the final work is a little worse, it would be acknowledged that it was done by no specialist.

Ok, I don't know exactly what is my argument here, so I'll just stop.
