You do realize that this kind of rant leads to AI designed to better emulate humans? It will produce the same flavor of rambling sentences, slightly off grammar, and other indicators.

Companies will not stop using AI, so the net result can only be a degradation of customer support to the same shit level that we had previously endured. But now there are no longer humans in the loop, and you can no longer have the signal to tell you that you should stop engaging with them.

Arms races have no winners, and it will be no different in this scenario. Heck, how do you know this has not already happened? How do you really know the second email was written by a human and not by exactly the kind of AI subterfuge that I just described?
