> And a funny personal anecdote, a colleague of mine tried to use ChatGPT4 when answering a customer question (they work support). The customer instantly knew it was AI-generated and was quite pissed about it, so the support team has an unofficial rule to not do that any more.

My team raised a support issue with one of our suppliers due to some unexpected API behaviour and got an unusually flowery reply that completely contradicted the API documentation... fairly sure that was ChatGPT.

Honestly not that bothered about LLMs as they could be helpful in customer support particularly when agents might not be fluent English speakers (or just help when you're trying to be polite in adverse circumstances), but some basic proofreading would help. And don't let it hallucinate APIs.
