Nah, it's still useful if the summary is usually right or mostly right. At the limit, it's not even clear that something can be summarized perfectly.
Consider that the alternative to reading the summary often isn't reading the entire text yourself. It's reading nothing.
Also, in my experience, these tools often fail when it comes to questions with a definitive answer. E.g. if you pass them a lot of text and ask a detailed question with a very clear answer, they often get it wrong. But when your question is vague like "summarize the text," they're very useful.
