Because that's how it feels to me whenever I try to use one. It gives back the same answers a clickbait article would where in the end turns out after 3 paragraphs of reading that the answer to your question was "no".

Did anyone actually manage to use one where it feels like you are speaking to another intelligent lifeform? For me every time it just feels like another search engine where instead of having to read through all the results Google gives me, I get it summed up in one place instead of having to click at links and go through each article one by one. But the information it collects is most of the time irrelevant or inaccurate.
