I'd be furious if I found out some professional I'd commissioned had taken a document based on my own personal data, and poured over it themselves looking for errors at the tune of hundreds of dollars per hour, instead of sumbitting it to ChatGPT.
Yeah, I think the issues presented will relate to uniquely tricky errors, or entirely new categories of errors we have to understand the nature of. In addition to subtle and rare, I think elaborately hallucinated and justified errors, errors that become justified and reasoned for with increasing sophistication, is going to be a category of error we'll have to deal with. Consider the case of making fake but very plausible sounding citations to research papers, and how much further AI might be able to go to backfill in it's evidence and reasons.
Anyway, I just mean to suggest we will have to contend with a few new genres of errors
