I like the idea of this consultant work, but I also find the idea that people are incapable of learning a new field because they missed out on lessons earlier in life outrageous and simply incorrect (I don't think the author was intentionally disrespectful here, they've just always been in a community where their life is on rails). Precociousness is one type of intelligence, and early schooling is valuable, but people can always learn, even at the highest level. It is unfortunate that most of our higher education/research programs for science are structured in such a way that entry into those programs is difficult for people that are older and need to maintain a good income. Really we'd need alternate program structures like those for many master's degrees, or more advanced online courses.
