When that AI shopping tool made to sell you couponed products pops up, abuse it. Ask questions about its products that any real human would answer in a normal way, that an AI simply cannot. This would get it through to them we don’t really want or need this.
By encouraging them by using the AI, you are generating justification for the cost, which doesn’t grow per user and time spent in a meaningful amount.
If you don’t use it, they will have wasted money on implementation and support, and then will have pissed that money away by ending it and having to hire people or switching to a non-AI chatbot.
You won’t bankrupt the company by using their AI garbage.
