Most of he problems we solve with computers are mundane - from batch programs to update files from data tapes in the 1960s to making a phone UI talk to a CRUD back-end in the present day. This kind of ordinary programming doesn't really require much computer science and never has. However, there will always be more interesting applications (or interesting sub-problems of otherwise mundane applications) that stretch the limitations of current knowledge and technology, and these will benefit from advances in computer science and from developers who keep up with CS research. But it has never been the case that every programmer needed to be a computer scientist.
