The authors focus on the citation inflation in younger scientists but that s unfair (it's only 1000 out of the 20000 in the top 10%). The reality is that older established scientists are much more advantaged because the people of their lab are sought after as collaborators , and they autonatically get an authorship as last authors by virtue of being principal investigators, even if they don't even take a look at the paper. It's thus not strange that they get 35+ authorships per year
