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.
