A long time ago in a place called "Appleverse," a company named Apple made some really cool things with computers and phones. These cool things are called "AI features" because they make our phones and computers think and talk like humans. But sometimes, things can be tricky, so Apple had to find ways to make sure the things our phones and computers say are good and nice, and not silly or mean. They used something called "prompt engineering," which is like giving your toys little notes to remind them how to play nicely. Apple also did a great job making money, and their "market cap" (which is like a big, fancy bank account for companies) was worth $3 trillion! Read from source...

1. Inconsistencies: In the first paragraph, it is mentioned that Apple's AI advancements are in the spotlight. However, in the next paragraph, it is discussed that Apple might charge up to $20 for its AI features, which seems unrelated.
2. Biases: The article seems to have a positive leaning towards Apple, as seen in phrases like "Apple' s already profitable services business" and "Apple offers various methods to unlock your Mac without a password."
3. Irrational Arguments: The article discusses the possibility of Apple charging users up to $20 for its AI features, suggesting that the high cost of AI development could prompt Apple to pass on the expense to its users. However, this argument seems irrational as AI development costs are likely to be a small fraction of the overall revenue generated by Apple.
4. Emotional Behavior: The last paragraph of the article shows emotional behavior as it mentions that despite recent market turbulence, Apple has held its $3- trillion status since June 2023, which seems to evoke a sense of pride or accomplishment.
