Copilot: Prints a list with, at best, 5% accuracy
I know some folks have the peculiar idea that search is dead in favor of AI, but if AI can't accurately find information, it is useless. As near as I can tell, Copilot finds 3-4 items (but rarely the SAME 3-4 items across runs) and calls it a day. It just seems like nobody is actually testing any of this stuff. Microsoft is actively destroying its credibility because it's offering a tool with a party trick but is utterly unreliable. I will, therefore, not rely on it.
