Fair point. What the author does mention is that if you have to do a lot of work getting proper results out of AI (and potentially contend with hallucinations), you may as well do the actual work yourself and be more confident about the end result.
That being said, I think part of the potential is repeatability. Once you've done the work of property prompting for the desired result, you can often save the adjusted prompts (or a variation of it) for later use, giving you a flying start on subsequent occasions.
