1. People wouldn't need to contact support if you just made quality goods and services. Outside of rare exceptions and inquiries, of course.

2. AI has not advanced enough to trust it outright, nor does it have a physical body. So it can't really do anything you wouldn't already just be able to put in the UI for the customer, without needing it's actions reviewed and confirmed by an accountable human. See: accidental truck giveaways.

So investing into AI support over making your business better is seen as misallocation. And using AI support instead of just improving the service is seen as inconvenient. And using AI support when it needs humans to do the support anyway is seen as inefficient.
