This is where I stop following. Businesses should focus on where they differentiate, and I really don't care how they generate signage if I can read it. I don't get anything by them paying Banksy to make their menu instead of having Gemini generate it. And if there is any connection to getting good value, it's the inverse: I'm more likely to get good value when I'm not paying for fancy advertising. See: every drugstore that puts generics alongside brand names for cheaper.
The worst generative AI posters and restaurant menus I'm seeing from newer small businesses do not instill the same feeling that I'm getting generic-like value. To keep with the drug analogy, they feel like the combo pills you find somewhere in the back of a gas station which combine 10+ random supplements to help with 20+ different symptoms. Especially for new restaurants where real reviews are limited, menus with terrible AI generated food drawings really give me the same ick - that they might not be providing any good value at all.
However, i do admit that part of this is also that i live in an area where there is tons of competition for most cuisines I'm interested in, so I can use menu quality as a differientiating factor in the first place. If enough places around me were using sloppy AI menus i would probably ignore it.
I'm saying I don't particularly value businesses that focus on things that are low impact for me. I'd rather my barista focus on sourcing good beans and making good coffee than paying someone to do a fancy custom menu for them. We see this all the time when we visit new areas. It's considered naive to follow whatever looks most glitzy -- every seasoned traveler will tell stories about all the tourist traps, and how the real quality is the hole-in-the-wall place all the locals gather.
What I'm saying is we shouldn't conflate quality with marketing and advertising, which is what posters are. You seem dead set on doing so anyway, and I'm not sure why.
AI-generated visuals aren't the first to go through this. I'd say the early-to-mid 90's "desktop publishing" went through this too - as soon as everyone could make ads and flyers cheaply with Word, everyone did.
If you can tell that it's AI, that's probably because it is low effort. Higher-effort attempts pass more easily.
(Of course, that also requires an understanding that there are ways to apply effort to making a short request; and believing that it would make a difference; and noticing for yourself that the first output is bad; and trying. Quite a lot of people seem to lack at least one of these.)
It won't die off until AI stops being used with low effort. Which it is the majority the time used for.
If a business markets itself with these AIgen posters, you get wildly different responses from different groups.
boomers that spend all their time on Facebook will think “this is such a nice pretty poster” and be oblivious to the fact it is even ai. Even if they knew it was ai they don’t care.
Young people will think it is low class/trashy. Some hate it because it’s ai, others hate it because the poster is ugly/busy/confusing.
