Yes. Because, the incentives for companies are too big to ignore. The math being done right now is $10/hr for voice support in (say) the Phillipines is much more than $0.10/hr having an AI do it, even factoring in the cost of some customer churn. And the risk of the latter for some services can be discounted to zero if the user has no viable alternative. Second, the best support line is one where no one calls in. So…
There's always a viable alternative. But not for customers who are always looking for the cheapest viable products or services.
So those customers will spend too much time and frustration with bad customer service, because they think it's outrageous to consider a competitor who is a little bit more expensive.
