Why have all-knowing customer-support AIs waste their time and resources talking with underwhelming human customers such as myself? It would be much more efficient for customer support calls to be made by all-knowing personal assistant AIs, which can surely explain the nature of the problem much better than me, as well as being better able to infallibly put in practice whatever the all-knowing customer-support AI suggested.

The AI will have more experience composing bullshit put-offs, but even less access to the systems that control the systems that are exhibiting problems customers currently experience. We'll see the problem of layered customer-service (where the first two layers have no power, other than to maybe turn on some pre-configured bonus/offset/coupon) made worse by further automation.
