I think this article fundamentally misinterprets Greg Stevens' article. He is not saying that anyone is bound to a field. What he is objecting to is the rejection of the idea of taking time to become qualified. Rob Rhinehart is attempting to do something he is patently unprepared to do, and if could have serious health consequences for adopters of Soylent.
I believe that if Rhinehart had spent enough time to become seriously well versed in nutrition, people like Stevens would not be leveling these complaints. Instead he is encouraging people to replace their entire diet with a product that is no more than 6 months old and whose effectiveness has only been measured by anecdotal evidence on a tiny sample size.
The Wright brothers spent years and years studying and perfecting their craft before they let anyone else try it. Perhaps Rhinehart should do the same.
I, for one, disagree with almost every claim in this article. I think the positions the author takes are too open to controversy to reach the top of somewhere like hacker news.
Something that no one has mentioned here, you will have a HUGE amount of free time at college. Far, far more than you will have if you go get a job.
If you are more interested in starting/continuing to run your own projects than working on someone else's, then I would- without a doubt- go to school.
