It's horrible feeling like the world has passed you by, perhaps even more so when it's forced on you by external factors rather than choices you've made. That being said, I wonder if you should challenge your assumption that it's out of date. I'm definitely clueless on whatever the latest JavaScript library is and whatever's going in machine learning. But my knowledge of foundational data structures, algorithms, and software development practices often makes me more valuable than somebody who is more "up to date". It feels horrible when someone uses an acronym I don't know, but it doesn't actually have much impact. Then again, perhaps you're right and it really is causing you problems - it's hard to give specific advice on social media because the async nature prevents good Q&A. Could you find someone that will coach you on it?
