Just on a side note. Negative synergy does not seem so uncommon with machine learning. We did some research maybe 10 yrs ago an human/ML based duplicate detection (for a municipal support ticket system) . Research showed that pure AI and pur human outperformed co-working. Human oversight often e.g. overcorrected machine work. I think it is a nice HCI problem to solve actually to amplify creativity and unique skills in such processes. Particularly if they can be to some degree repetitive and tiresome.
