That is different because all of the players I mentioned have credible, near-leading products in the AI model market, whereas nobody other than Google has search results worth a damn. I wouldn't recommend anyone squander their time by checking Kagi or DDG or Bing more than once.

I don't use google. Believe it or not, I get better results via Bing (usually via DDG, which is a frontend for Bing). But I asked the rhetorical question expecting the answer you gave. These people use ChatGPT only for the same reason you exclusively use Google.
