It's a convenient way of looking at things. Saying that it's good at one thing and bad at others. What I have come to realize with LLMs is that anywhere where experts deal with them, they are very aware of their shortcomings with respect to someone's area of expertise. Sure, you might say they're good at producing text, yet a journalist or someone who simply writes a ton might be able to spot generated text in an instant. The same way a photographer or painter can spot these statistical methods instantly. Rinse and repeat for coding, translation, medicine and all other tasks specific to current societal roles. That is not to say that you need to be an expert to spot LLMs or other generative ANNs, it comes down to attention and what you condition yourself to be attentive to. Of course pictures or code, or whatever will be convincing if you treat these things as secondary, like a doctor would treat creative writing as secondary to their job though necessary or a biologist would treat writing python scripts.
