Back when you could slap together some divs, add a sprinkle of CSS, throw in a jQuery carousel, and boom—you're a "full-stack developer." Now? You need to know React, Vue, Angular, TypeScript, Node.js, GraphQL, Docker, Kubernetes, CI/CD pipelines, three different state management libraries, and somehow still be expected to center a div on the first try. The barrier to entry has gone from "can you Google stuff?" to "do you have a PhD in JavaScript ecosystem archaeology?" Grandpa dev here is reminiscing about the simpler times when jQuery was cutting-edge and your biggest worry was IE6 compatibility, not whether your build tool's config file needs its own build tool.
