People have been advertising their small business or event with crappy clipart and a complete lack of design sense for as long as we've had access to personal computers. Didn't stop people making these things a success.

The current wave of stuff they're making with LLM tools just all have this uncanny valley feel where all you can see are the slop markers and, for me at least, it's incredibly distracting from what the thing is even trying to tell me.

Do I think there's a meaningful loss of business for people using LLMs? Probably not, but I'm not alone in just now ignoring any product, service or event if it uses LLM image generation to advertise it.
