That depends on the purpose of the image.
If it's used to create a false narrative (like a deep fake), sure, you should care. But if it's used as an alternative to a stock photo, or as an easy way to make an infographic then no, I don't think you should care.
And when an LLM starts hallucinating, and I emphasize “when,” is that not the same issue as creating a false narrative?
> you should care
Why should I care? The world is full of false narratives.
How can I have the bandwidth to care about everything all of the time?
I swear that more than half of the complaining that I find here comes from priveledged people bike shedding over inane topics, and who have never had to really worry about serious survival-level (how am I going to eat today?) issues in their lives.
