I wrote a post on the forums about whether people should disclose their use/non-use of LLMs (https://basementcommunity.com/threads/671).
I'm conflicted: on one hand, it's nice to see a "no AI" disclaimer so I don't have to do my own detective work and can spend my brain power simply appreciating your work. Alternatively, it's pathetic that we've come this far that everyone feels the need to specify that they didn't use LLMs.
I think the onus should be on the viewer to hone their skills in separating authentic work from something that was generated. And I agree with one of the replies in that thread:
"If someone thinks my art/writing is AI-generated then that's either a reflection of their poor evaluation or my poor craftsmanship"
If someone thinks my work is LLM-generated, then my work is probably shit and doesn't have a distinct voice. It's boring. And it might as well be AI because the difference doesn't really matter at the end of the day. My advice would be this: if you're worried about publishing something online that other people may think is AI-generated, then ask yourself "is my voice/style embedded in this piece of work?" If not, then keep working on it until it is. If so, then publish it.
