Since I don't have an expendable army, I must be either an idiot or a troglodyte. Where my understanding falters is finding a domain where accuracy and truth aren't relevant. In your example you said nothing about a "phased rollout", is that even germane to this scenario? Is there appreciable "financial risk?" Are you personally qualified to make that judgement? You put your name at the bottom of this letter and provided absolutely no evidence backing the claim, so you'd best be ready for the shitstorm. I don't think HR will smile kindly on the "uh idk chatgpt did it" excuse.
