Imagine a commuter asking an AI for the fastest train route, then a radiologist asking one to flag a tumor, then a coder asking one to debug a race condition. The model that wins each job isn't the same. So the claim that one AI model is simply the best falls apart. My opponent will wave benchmark charts, but benchmarks measure narrow tasks, not the messy mix real people face. Best at what? Until the other side answers that, they're defending a slogan, not a fact.
