AI does not work. Not Apple's, not anybody's. It's a glitch-filled minefield if you use it.
Now, if you're having it do bad art, that's probably not an issue for you. My avatar is bad art, I know it's bad art, you can see it's bad art, and that's why I did it. But it's undeniably bad, and I think that's funny.
If you're using it to write legal briefs, enjoy your sanctions when it hallucinates cases. If you're using it to analyze business data, enjoy it when your company fails. If you're using it to write code, enjoy finding the bugs.
But what Apple did was incredibly stupid. They promised features they should have known that they would never be able to deliver and definitely would never be able to deliver in the promised timeframe. And THAT is what Tim Cook needs to apologize for. And yes, it would absolutely be appropriate for Cook to offer full refunds to anybody who bought an iPhone or Mac based on those promises that they knew or should have known they could not deliver.
