So let's ignore the headline and most of the article's content, since it's really not relevant to the most interesting supposition of the article. First, two definitions, from the author: 1. On-Demand Learning: Learning done to solve a specific problem as it is encountered 2. Preliminary Learning: Learning done for the sake of a broad understanding of a subject I disagree with the naming, but we'll roll with them for brevity's sake. The author worries about on-demand learning being applied to the exclusion of preliminary learning. Put another way, too many people read tutorials without reading general information. So, the solution is pretty simple, on the face of it - make sure you're regularly learning broad areas, not just specific solutions. Read a variety of books. Acquire a broad base of knowledge.
