1: Actual AI does not exist. Stuff like ChatGPT is just making versions based on whatever it has access to.
2: Machine Learning (which is what "AI" is currently marketed as), is a real thing with real uses.
3: Using human language is one of those things. That's what an LLM like ChatGPT is. It can use language. But it doesn't understand what it is saying. That's why people fall for it.
4: Give me examples of actually useful ML applications? Protein folding, image identification etc?
