A huge problem. I think AI-based customer service is more negative than positive in general. In my opinion in this way we first of all entrust an operation that needs to be timely and above all empathetic to AI; secondly, although it is faster to train a model to become a very good customer assistant, thereafter a continuous human intervention of monitoring, improvement and error correction is required. So in the end, in addition to not having a customer assistant capable of “being close” to the customer and understanding the finer nuances of a customer's request, this approach leads to inefficiency and slowdowns in the medium to long term.
