You are paying, the same way you paid for stack overflow.. you become part of the process, ask follow up questions, deepening the knowledge of the system.

The same applies to AI. The old learning material is gone, your interaction is now the new learning material and ground truth.

PS: Hourly rates for sw engineers: Range:€11 - €213 - so one hour on stackoverflow, searching and sub-querying resolving problems costs you or your employer up to 213€. It really depends on what you have negotiated.
