Another interesting article in The Economist: the disposable academic – why doing a PhD is often a waist of time.Although the author is mostly right I think she misses the point that PhD students can also become entrepreneurs: they master a technology and, contrary to most academics, they have the incentives to take it to the market.I believe that we must re-structure our doctoral programs to include knowledge valorization together with knowledge creation. All PhD students need to know more about markets and intellectual property protection and acquire basic management skills.http://www.economist.com/node/17723223
