ChatGPT can produce output that sounds very much like a person, albeit often an obviously computerized person. The typical layperson doesn't know that this is merely the emulation of text formation, and not actual cognition.
Once I've explained to people who are worried about what AI could represent that current generative AI models are effectively just text autocomplete but a billion times more complex, and that they don't actually have any capacity to think or reason (even though they often sound like they do).
It also doesn't help that any sort of "machine learning" is now being referred to as "AI" for buzzword/marketing purposes, muddying the waters even further.
