I don't know much any the author but the difficult parts of my job often involve interacting with pretty complicated code.
Either very optimized / specialized or a lot of math etc.
It seems like all the use cases are for tasks that are quite easy to timebox and don't take that much effort.
I appreciate using new tools to make these parts more efficient. But, if you are spending hours a day doing these types of tasks you might be easily replaceable anyway.
Expert uses tools effectively. Beginner misuses tools to bodge the same job.
I used a fretsaw once long ago, and thread cutters. Amazing devices which look like "how hard could it be" and turn out to be incredibly easy to use badly. I completely failed at both tasks. I was shown how to use a woodlathe and like to think given 10 years could succeed.
This expert uses ChatGPT to inform decisions they make. They don't just apply the output, they reflect on it.
Several of the jobs are "make conform to a specified pattern" which a statistical model is going to be good at.
Give the same tool to a neophyte who doesn't understand how to introspect on what it produces. Bad outcome likely.
