I'm not so sure, I think it could go the other way. The vast majority of support cases should be handled in an automated way. I had an issue with Vercel recently where I argued that a bill was incorrect, and the agent produced and offered a refund by itself - that was interesting.

You obviously need humans but they can be freed up to deal with the more complicated cases.
