You know, lately I've been thinking about the languages I learned this past few years. As of now, I'm nowhere nearly good in any environment thanks to my stupid brain following the "language love boat" preaches. Couple days ago I decided to shut my eyes off articles that compares programming languages and decided to stick with Java and Ruby. I don't plan to learn 10 different programming languages for the rest of my life unless I happen to get an offer in a company where they would want to train me in their technology. I have no plan to be a software developer for the rest of my life because that is a bottom-line job. It's useless really. Especially when there are too many effing opinions in our industry such as: - We prefer young people (remember, y'all going to get old at some point, you'll be out of the game soon) - We prefer TDD, Scrum, and Agile (those of you who dislike TDD will be crossed out from this list) - We only do games (those web developers are out) - We only do web-development (don't know HTML/CSS/JS? get out) - We only do internal IT (you're a software product guy, you won't last long here) - We do "Digital Social Media Marketing Branding SEO" (you're just a PHP developer, go make something) - We do SAP, PeopleSoft, and Oracle Financial (you're not qualified even though you know .NET) - We do embedded (web developer and enterprise developer, the door is right there) - We only use Apple (not an Apple fanboy? doesn't worship Jobs? out please) I'd rather spend my time learning the business domain, leadership, management, networking and how to live a life and achieve happiness than learning LISP, C, C++, HTML, CSS, Python (I know a few things about Python but by no means I can be qualified to work in a startup that uses Django). I don't want to be 50 years old hacker unemployed (due to age) and have no social skill to convince people that I'm still worth. Besides, I want to have a retirement that doesn't bother my kids's financial situation. Do you have any idea how long it takes to learn and master a programming language and the ecosystem (libraries, tools, the community, etc)? It's a life choice that I decided and I don't think you should look down at other people choices.
