tl;dr: "Hey, your CV says you've been doing all kinds of interesting stuff with Java..." "Oh you also use some of these modern tech tools to stay in touch with the community broadly, that's cool" "Can we hire you as a Senior Dev or Project Lead for our enterprise app used internally by our 10,000 staff?" "Great, hired". Are you trolling here mate? (it's just such a strange question that I had to ask) Most Java guys from the 90s shouldn't (or at minimum, I hope they don't) give a damn about the new paradigms enough to keep following the trends over stability. You've lived through the Java, PHP, Ruby and now JS explosion. You should probably know by now that the tools don't matter as much as how well you use the tools in the given situation. Don't waste your time with web stuff professionally(if you enjoy learning it, then keep doing so and do web things part-time). You have Java, which automatically tells someone like me that I could easily place you in an Android app developer role and you'll be building stuff more robust (experience) and just as quick (familiarity) as the young app guys. Forget the consumer side as well. Big enterprises seem convinced that they need apps for their employees and you've dealt with the bullshit of enterprises, so either become an enterprise Android consultant (nobody gives a damn how old you are when running your consulting business and enterprise will value your age in some cases) or find a job at some company that either builds these apps or a company that has a few of them internally for their +50,000 staff contingent. It's weird trying to give someone that is clearly in their late 30s/early 40s advice, when you probably have a ton more technical advice to give to young guys.
