The argument is that the current peer review system is becoming inadequate. Here's a list of some outstanding problems:   \begin{itemize}  \item Research is becoming more complex and more collaborative. It is less and less likely that just one or a few referees can have the necessary expertise (and the time) to properly handle modern day articles. \textbf{Put Put  it simply, the {the  average number of authors per paper has been steadily increasing in the last few decades [ref], decades,  but the number of referees/paper referees per paper  has not.} \item "Publication pressure" and the "funding race" mean there is a steady increase in the number of papers that need to be refereed. This need can not be easily matched, since \textbf{scholars who need to publish more have clearly less and less time to be dedicated to community service} (in a "single referee" system the review process is very time consuming).  \item Cases of peer-review scams, mostly from predatory open access publishers, have been increasingly reported in last years. Basically a number of journals, exploiting the "publication pressure" climate, have been accepting articles quickly, with\textbf{ little or no peer review at all}.
