Generalist vs Specialist: Range by David Epstein, Book Review
David Epstein's book is solidly grounded in the non-fantastical real world. It makes the case that people who have experience in a number of different areas (generalists) have some advantage(s) over those with deep expertise in a single field (specialists). This is the case even as many career fields insist that their professionals get ever more and more hyper-specialized. This can cause those specialists to miss new ideas or connections to other fields which would have been beneficial.
