In recent months (I don't use it enough to confidently state when the change occurred) Google's LLM summary more often answers the wrong question rather than confidently answering the question wrong.

If it answers and the answer is for what I asked, it is right much more often than not. With that said, "trust but verify" is more like "don't trust and also verify" anyway, which is the same metric that should be used for most websites.

That is why I turned off the AI summary on Google. Useless 90% of the time, takes up space on my screen.
