I can see the argument here for sure. But it's not up to general society. Corporations will do this first. Think nearly all support chat and calls as a start. When you call now you get a shitty robot that you have to push buttons to get through, or chat that you have to try and get to a human. Those would be replaceable today, and save enormous amounts of money. All that takes is a small LLM a corporation could train on their products/services.

Decision makers that see the dollar signs absolutely will. They outsource products overseas with inferior quality because they don't care. They reduce consumable product sizes and charge more money for them because they don't care. When their quarterly profits go up, they don't care how the customer feels.
