What is best for your career given that the future is -- by definition -- not knowable and that the past and present are not necessarily indicative of the future? Go deep (specialize) just enough to be unquestionably proficient, but not enough to be one of the world's foremost experts. Go broad (generalize) just enough to be learned (well-informed) in discordant technologies, but not enough to be omniscient (all-knowing). I call this type of a person a "genspec", a generalist-specialist. For example: 1. It's more useful to learn functional programming, object-oriented programming, procedural programming, etc., than to learn e.g., 3 different object-oriented programming languages. 2. It's more useful to learn embedded development, mobile development, web development, etc., than to learn e.g., three different mobile development platforms. 3. It's more useful to learn e.g., 3 different OSs than to learn e.g., 3 different distributions of a single OS. Optimize yourself for change, adaptability, and continual learning of many materially dissimilar topics.
That's what's best for your career. |
