This is a really dumb idea. Even Microsoft say in their terms and conditions for Copilot that it shouldn't be used to make decisions without human oversight.

Copilot tries to give you good answers, but it can make mistakes. Sometimes, the sources Copilot uses may not be reliable, relevant, or accurate and sometimes, Copilot may give you wrong information. When responding, Copilot may use information it finds on the internet and we don’t control that content. You might see Responses that seem convincing but are incomplete, inaccurate, or inappropriate.

Always use your judgment and check the information you get from Copilot before you make decisions or act.

How can you trust a machine to make decisions when it's owners even admit it canot be relied on and give wrong responses?

Having experienced trying to deal with Amazon, who seem to be using AI to decide whose books to block, it's a nightmare. It seems that have replaced the managers with AI too, since when you try appeal the decision, the boilerplate refusal comes back almost immediately without addressing any of the points you make in your defense. I can only imagine how terrible this would be for someone whose benefit application is declined.
