Fat shaming doesn't work. It can maybe work, sometimes, on an individual level, like if you're a big enough dick to your friend or partner maybe you can get them to lose some weight. But the problem we (society) have isn't that your spouse is fat and my friend is fat, it's that everyone's friend and everyone's spouse is fat, and we (as a society) have already tried being mean to all the fat people and it didn't work. Show me the incentive and I'll show you the outcome. You can't set up a society awash with processed foods which are addictive by design, force everyone to use a car to get to the store/work/school, refuse to educate children on how to purchase and cook healthy foods, and expect everyone individually to recognize these flaws in our system and make a conscious effort to counteract them in their own lives. Maybe some people will do it, good for them, but the average person will do what's easy. If you want a healthy society, you need to make being healthy the easiest thing.

If your coworker keeps asking you to review merge requests filled with garbage code they copy/pasted from an LLM, sure, shaming them might be part of the solution. But if people are turning to AI because it's too difficult for them to get certain types of emotional validation in the physical world, making them feel bad about it probably isn't going to help.
