I've worked in the field of Contact Center AI for almost 10 years now. Rough order of magnitude you can expect to deflect around 30% of inbound contacts with an AI chatbot. You can also expect to reduce agent Average Handle Time by 15-20% using AI enabled semantic search and workflow automation. This is ballpark, if your contacts are simpler you can do a little better, if they're complex you'll do a little worse.

The problem is that vendors are telling companies they can eliminate 80-90% (maybe even 100% if they can keep a straight face) of their customer service agent jobs with AI, and that is nonsense.
