I honestly don't think they'll even quietly go back. It's clear "customer service" is becoming something that isn't considered a return on value, so they're shutting them down all over. Customer service will be the number one thing replaced with AI and they won't go back on that.

Customer service for the last 20-30 years has absolutely been nothing but a shield for corporations to hide behind while screwing their customers. Low paid phone jockeys have to deal with people furious at being fucked over by conglomerates like Comcast. There is no way to contact anyone further up the chain, and that is deeply purposeful.

They record all the phone calls, but they refuse to learn anything that benefits the customer from them. All they do is deploy psychological tricks to try to get the customer to be happy while not actually rectifying the problem. It's always a purposeful half-measure that has been deeply researched to calm people down and accept the big unlubed dildo in their ass like they should.

So yeah, the "customer service voice" will be long gone to be replaced with increasing shitty "customer service AI" with no human to talk to, and if you get lost in the shuffle and put in a digital black hole, well, "go fuck yourself" is clearly what they'll be telling you. They already pretty much do this (especially Google) but it will become increasingly pronounced and difficult.

Clawing back anything that corporations have stolen from you will increasingly become an exercise in total futility as you're stuck in an endless AI loop that refuses to give you options that actually address your issue.
