If I had a great idea and an investor was $100k confident in the monetization of it, I would probably drop out, too. The author's whole premise is that dropping out is universally bad and should be discouraged, and that staying in school is universally good. Neither are true.
The article also misses the point: Where might we be if some of the 'usual celebrity dropouts' hadn't dropped out? What if they had said, "I'll get a real job first, then work on my idea." The world might look very different.
Non-Ph.D. entrepreneurs and academics can peacefully coexist.
EDIT: I concede to gxti that my statement about the author's premise is false. I stand by my other opinions: The scholarship is a neat idea and will not convince most people to drop out.
