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.
Most of those AI chat bots have no AI in them. It is just the latest trend to sell chat bots to replace humans.
If you really want to rally against AI chat bots, get it to say something the company doesn’t want it to say like “if you buy X you get y for free” but when the store doesn’t honour it you take then to court because it has been ruled companies need to honour information from their websites.
