I think it's more prominent and damaging there on account of all the churn, combined with large amounts of stupid money. Mobile native developer? Might be something new you want to get familiar with every couple years, but really you'll likely be OK, career-wise, if you sleep on it for another year or two unless you actually need it. C++ developers aren't chasing brand-new frameworks to stay hirable, generally. Java and C#, most of the ads seem to be "have experience with [eight-year-old 'new' thing that's basically an ecosystem-wide standard now anyway], plus a bunch of much older things", and those two alone are a really high percentage of all software jobs.
