This is purely anecdotal, but ten years ago, or so, I was involved with a company that sold and installed call center solutions for hotels, casinos, and other such businesses. Though completely out of that industry since then, I am still connected to a lot of those companies/people on linkedin and all I see from them are ads and posts about call center AI. I don't believe that it is fully there yet, but it is coming and is not only motivated by the cost savings from staff reduction but also by the poor quality of call centers that have staff located around the world and are non-native speakers.
For every job lost to AI new ones will be created. The U.S. alone is in need of/and is short of 200,000 AI technicians *NOW*.
I believe it'll come bit by bit instead of in one go. AI might take over boring jobs at first - people sticking around where things get tricky or customers need reassurance. Swapping everything out seems kinda distant right now.
