Many people justify their choice of pursuing graduate school by a desire to explore new ideas and satisfy their intellectual curiosity, an euphemism for goofing off.
These students use graduate school as a cultural hack… they turn what might be perceived as an asocial behaviour (e.g., spending 4 years writing a Perl compiler in JavaScript using Bayesian inference) into something that is tolerated and even encouraged.
I think we need outlets where such smart people can go and do their things for a time. Indeed, most corporations do not want to collect employees who write Perl compilers in JavaScript using Bayesian inference.
College can be a good place to park smart people until they find something productive to do. And the hopeless ones become college professors.
Wait, Perl compilers in JavaScript using Bayesian inference. It may be the next big thing! Just ask Kurzweil.
On a somewhat related note, I came across this at the same time… http://scienceblogs.com/principles/2015/02/27/this-is-not-what-i-want-as-a-defense-of-the-humanities/
Would you hire someone who just got out of high school?
The really hopeless ones compete against hundreds of other PhDs for academic jobs in the middle of nowhere. And lose.
