Look for changes in actual tasks, customer expectations, approved tools, and training requirements. Industry associations, employers, and people doing the work can help you understand the difference between an interesting experiment and a process that is becoming routine.
Keep a simple note with three headings: what changed, where I saw it, and why it might matter to me. Check more than one source before acting on a major claim. Over time, this creates a grounded picture of your field without requiring you to follow every technology story.
