❌ Things ChatGPT Cannot Do or Struggles With (2025 Edition)

🧭 Cannot Handle Emotions or Ethical Judgments

• Designed not to delve into value judgments such as “Is that right?” or “What do you think?”
• Can provide superficial, empathetic-sounding responses, but does not understand actual feelings or context
• ⇒ Human support is essential for mental health care and in-depth counseling

🎨 Its Original Creativity Has Limits

• While it excels at generating ideas and remixing content, the ability to evoke genuine “emotion” or demonstrate “originality” remains a human strength
• Even with stories and poetry, it remains within the scope of pattern learning
• ⇒ For creative work, it’s recommended to use it as a “starting point”

🧾 Not suited for “questions with no single correct answer”

• It struggles with questions where answers vary by person, such as those involving philosophy, religion, or outlook on life
• On controversial topics, it remains neutral, making it unsuitable for decision-making
• ⇒ When deciding on opinions or policies, human discussion and careful consideration are necessary

🔒 Security and privacy cannot be guaranteed

• It does not guarantee that the content of conversations or files is completely secure
• It is unsuitable for handling sensitive information or for uses requiring legal judgment
• ⇒ For tasks such as checking passwords, personal information, or contracts, it is essential to consult a professional

🧠 Cannot learn or grow on its own

• ChatGPT is not an AI that learns from user experiences or new information
• Acquiring new knowledge or accumulating experience requires updates from OpenAI
• ⇒ It is fundamentally incapable of “growing through use” like a human
