Yes, significantly - even when adding in vendor costs etc. In general though it is best at answering routine questions or ones a customer could get by reading the docs. The net result then is the ones left for the humans are the harder ones.

We’ve also heard from other companies that as the first line paper cut questions get answered, customer adoption increases - which further increases the “hard” support questions.

Lesson learned for me on that one that was rolling out a support agent led to both a better experience for our customers and an increased need for talented human engineers.
