I recently had a conversation with a large tech company that went basically "We saved a ton of money by replacing all of tier 1 support with AI chatbots so that the problem can be identified and routed to the correct tier 2 person to triage before it goes to a tier 3 person if it needs to. Next we're replacing all of the tier 2 people and the only time we have to get an expensive human involved are the weirdest/most difficult problems." My reply: "where do tier 3 people come from if they have no experience at tier 1 or 2". Queue the sound of crickets...
