> There's substantial churn, absolutely. How many popular web frameworks have there been? But substantial change that would be catastrophic for a career? No. Finally! In my whole career so far, I could maybe name you about 2 frameworks that I'm both a) actively aware of and b) know when would be a good idea to use. I have not struggled to find work. What I consider to be _real_ skills, such as knowing how to work to a deadline, prioritise, work with difficult people, research, communicate, knowlege of good coding standards some good solid fundamental CS understanding, only seem to improve with time. I'm not saying to stop being curious about whatever floats your boat, but it's not like you're going to miss out on 'the next big thing' by sitting out a year (or, in the case of some of the best engineers / managers I know, moving careers for a decade).
