If you were to mix ChatGPT with premade blocks and a WYSIWYG editor you could get very far. It would be quite a lot of upfront work if you were actually intending on automating the full site creation rather than a general wireframe, still doable.
But, nobody really has a job like this in the front end. They were all replaced by Squarespace/Wix/Webflow/etc years ago. Which seems to confuse people who aren't really in web development, and where Josh Comeau is mainly making the argument from (against the social media idea that "front end is dead").
I think the description as such will be the difficult tasks, followed by fine tuning your description if ChatGPT's result isn't correct.
