In this third and final part of our interview, we talk with Dave about his life after retiring from his life as a publisher. We start with his thoughts on agile (both as a noun and as an adjective) as well as the use and value of spoken and written language in the digital age. We talk about society's relationship with the book and whether there is in fact a future for bookstores as we currently know them. We wrap up with what advice Dave can offer the next generation of programmers.
