worth clarifying "chat" is actually (linguistically) completely separate from a shorthand for ChatGPT. Livestreamers (e.g. on twitch/youtube) often talk to "chat", the people watching. Visually, they're just narrating actions etc to a 3rd party who is not present.
This has leaked into (some) younger people's vocabulary. A particular example is saying "Chat is this real?"
