I'm personally using it because SEO bullshit has ruined search engines. AI can still sift through bullshit search results, for now. The key is assuming the AI lies and actually reading the page it links, because it'll make up facts and summaries even if they directly oppose the quoted source material.
I fear AI tools will soon befall the same faith as Google (where searching for an obscure term will land you a page of search results that's 75% malware and phishing links), but for now Bard and Bing Chat have their uses.
So they create the problem by increasing ads and spam in the result, then sell you the A.I. solution. What's next? Put more insidious ads that still answer the original query but have an oblique reference to a paid product?
It can generate output, but I'd not want to use it for anything because it's all so poorly written.
