Around here, e.g banks are big on Java, and banks are not going away anytime soon, nor is their Java code, which represented huge decade-scale efforts to move away from COBOL on IBM machines (both of which seemingly not going away either). And that's only one data point. Sexy? nope. Hot new thing? neither. But the jobs are out there. Similarly that mention of RoR being "in danger" seems incorrect. It's just that Rails is not the topmost big player in the market, and I don't think it ever was, even at its early peak. Sure it made rounds in the news and had a big impact but even back then it certainly wasn't The Tech That Everyone And Their Dog Uses. That's fine. A tech doesn't need to be in the top 3 market leaders to be useful, successful, and lively.
