> If "this is the last game for Alex Morgan" wasn't included as any part of the input/prompt, how on earth could the AI summary have come up with this for inclusion in the game recap?

It couldn't, which is the problem. One of the big selling points of generative AI is to cut people out of the process of writing. If someone actually has to watch the game and describe what happened in the prompt, what's the point of the technology at all?

This is what an application of generative AI looks like: using low-quality input to generate something that looks like an article. This is our glorious future, brought to you by OpenAI.
