I&#x27;m always worried that it&#x27;s <i>not</i> great for me professionally. Because the &quot;cool kids&quot; are always off learning the hot new thing, and I can do what I need to in the &quot;old&quot; thing, and so I don&#x27;t learn the hot new thing.<p>Aren&#x27;t I, as an engineer, supposed to be constantly entranced by the bleeding edge of technology? Whether it&#x27;s the latest lisp Dialect, the latest functional programming language, the latest NoSQL database, or whatever the latest is?<p>Granted the nature of my work is such that I wind up using tons of new technologies every new year, but I don&#x27;t go out and experiment with them with no particular use in mind.
