  1. AI writing often uses vague and abstract words instead of concrete details. This makes it feel less relatable and real, unlike human writing that includes specific experiences.
  2. The choice of words in AI writing tends to be bland and overly formal. It avoids strong emotions and edgy language, which can make the text feel lifeless.
  3. AI lacks genuine sensory experiences, leading to descriptions that seem disconnected from reality. It can mention feelings or sensations but lacks true understanding of them.

  1. Generative AI has shown some progress in handling specific prompts, which is a win for some, but it doesn't mean it has mastered complex tasks like compositionality. Success on easy tasks doesn't prove overall ability.
  2. There are still many cases where AI fails at tasks that involve understanding parts and wholes, suggesting that its understanding is not as robust as claimed.
  3. Judging the AI's overall capabilities based on a few successes can be misleading; it's important to look at a broader range of performance to get a realistic picture.
