The internet didn't ruin customer service. Companies, in the form of the executives that run those companies, chose to slash and burn customer service down to the minimal possible. Now all we get is an email address that generates an automated response. Maybe somebody at the company someday will read the email and if it looks important create a Jira ticket which will pile up in the backlog with the rest.

That's a pretty big stretch. When a customer calls for customer service, it's usually some kind of edge case that normal procedures can't handle. That's not an AI specialty.
