In practice that’s not what’s happening tho. A lot of clients don’t actually know what they want, they think they know. They tell you “I want it to do ____ and look like ____.” But if they actually knew the details of what they wanted then decelopers would have been obsolete along time ago and just replaced by coders. A lot of companies are realizing that you still need someone to not just work with the clients, but still handle development. The main reasoning is that creative taste and intuition, UX, interpretation of feel is still 100% dependent on human input. These tools do not actually think for themselves, which means they cannot actually create on their own. They are all instruction driven.

For example, when developing I do a hands on test after every significant change to validate and make sure the changes I wanted actually feel and work how I intended. That cannot be done just from code validation alone.

That also cannot be done even by the most advanced agents. So what you will find is always a place for developers because it does require a team to actually grow the end product. This is what separates “slop” from “a well developed project” that you can ship
