AI can do any job.

It can't do every job, or else it would have happened. There's a lot of limitations that prevent it from accomplishing even the most basic facets of some jobs.

Ironically, especially the manual labor jobs not already replaced by robots are some of the toughest nuts to crack with AI. For example, any task where a human starts to have a hard time just by putting on some gloves, we don't have ways to feed the AI the usual set of inputs that the human is acting on that is needed to properly imitate the behavior.

On the front of dealing in fact based work, LLMs don't really deal in 'facts' but facts are very highly correlated to the narrative, so it can frequently do a passable job, but it is factually incorrect a fair amount of time and if the facts actually matter, then it's a tricky scenario. If you can hook it up to a feedback loop where mistakes are both harmless and fed back into the model for a retry, then you can significantly mitigate this drawback, but it's not always feasible to do this.

Now perhaps it can 'do' every purely fictional output of text, audio, images, and video, which would be the topic of the post. The stuff we were kind of hoping to be freed up to do as fun and rewarding art. Instead, it's the first thing that is 'nailed' by AI as far as corporates are concerned freeing up people to be those plumbers and HVAC technicians instead of doing art, and we get stuck with the most milquetoast slurry of slop to consume instead.
