This sales manager didn't know that neither he - nor his customer - properly understand the product until he was specifically called out on it (by me, as it happens. At least the boss laughed). Are we expecting GPT-X to sit in on Teams meetings and ask questions like that, too? Sales manager literally did not know he needed to start asking questions about the product. Tech team were calling BS on it as soon as he reported his conversation with customer.
