You are comparing apples and oranges here. Large-scale fusion power is still a theoretical industry. Human editing/oversight of Wikipedia is a fact and is happening today. The question of the site's accuracy is simply a matter of how many people are brought to bear on the problem. That is the theoretical aspect of what I pointed out. Assuming OpenAI's study is accurate (and they certainly do not have an anti-AI bias), LLM AIs have a built-in limit to their accuracy, which no degree of work can correct, short of a completely novel AI model.
