If a certain technology is very interesting/promising, then stop wasting large amount of time on Reddit/HN seeking advice/opinions about _whether_ you should learn it or not. Instead, find 3 or 4 hours to finish some introductory tutorials to actually get to know the thing. This 3 hour work will relieve you from weeks, even months, of uncertainty/lurking, not to mention the possible anxiety due to not understanding people's conversations. By the end of the 3 or 4 hour studying, you actually learned something, and can decide confidently on your next moves. For example, as a Vim user, I always wanted to learn Emacs, and god know how much time I have wasted in reading those fun editor war threads. Last month in one evening I finally installed it, finished the built-in tutorial in 2 hours. Then I installed Spacemacs which has been hot recently, I spent another 2 hours playing around, learning how to configure it. In 4 hours I gained a pretty solid idea about Emacs' setup, how to do common tasks, some useful packages, including the annoyingly frequently mentioned Org-mode (ok, it is indeed powerful, e.x., the calendar thing is pretty rad). Emacs is extensible for sure, but I know I don't have time to learn it now. I also know in the future I will start with default Emacs, not Spacemacs, if I renew my learning. Anyway, I have this problem of waiting and lurking. IMO spending a few hours finishing one or two tutorials _today_ is a much better approach than weeks/months of evaluating through reading Reddit/HN posts. For example, even if you apply this method conservatively -- once every 15 days, you will accumulate _hands-on_ knowledge on more than 20 new technologies in a year.
