AI models write code better and faster than devs, but what AI cannot do reliably for your specific product is make the fundamental system design decisions like:

"Where should this piece of data actually live, who owns it, and what happens to the user experience when the network fails, the user refreshes, or a link is shared?"

The modern frontend engineer’s primary value has shifted from writing code to evaluating trade-offs.

To build fast, resilient interfaces, you need to treat state management as a distribution problem across three distinct domains: Server State, Client State, and URL State.
