For some it already has. I know several people who use ChatGPT as their go-to for search now.
I’m still a mix. I use Kagi, but almost always throw a “?” at the end of my search to get an AI answer, but will often use that in conjunction with the normal search results, or the references provided by the AI.
If it’s something that will have follow ups, I’ll either jump into the Kagi Assistant or use ChatGPT.
The way things are going, AI replacing search for most wouldn’t surprise me at all.
