I bet the guy who wrote this article is not a PhD holder. He wouldn't understand the fact that the learnings of a PhD work cannot be replicated many times by the same person easily in our lifetime.3 years (PhD to be dopne full time) is a little more than 4% of our lifetime (considering 65 as life expectancy)..!! TCA Srinivasa Raghavan should try a PhD first before giving expert comments..!!
