You're not accounting for teams already being understaffed and overtasked in many situations, with some AI tools allowing people to get back to doing their jobs. We aren't expecting significant headcount changes, but we are expecting significant performance and quality improvements for the resources we have.
The reason that caused the team to be understaffed and overtasked has not gone away because of AI. I am expecting the team to stay understaffed and overtasked, for the same reason it was before: it's less expensive. With or without an LLM summarizing phone calls.
