The author either has not done his PhD or exploting young phd students for his publication. This idiot doesn't even understand the people in science at least are fedup with the already existing system of phd studentship. They spend at least 5-7 years on an average fighting with the system doing hard work for their phd and after that you expect them to have expiry date for their PhD's. If the policy is like that then I have a billion dollar brain which I don't wish to waste on getting the degree and keep it alive. No one would like to do phd... the author does not have even minimum common sense.
