I get Copilot to bail on conversations so often like your example that I'm only using it for help with programming/code snippets at this point. The moment you question accuracy, bam, chat's over.
I asked if there was a Copilot extension for VS Code, and it said yup, talked about how to install it, and even configure it. That was completely fabricated, and as soon as I asked for more detail to prove it was real, chat's over.
