For me, google searches are defaulting to "AI mode"
I just asked it the same question on 2 different devices.
The question I asked was harder than why is the sky blue. I asked it "who was Edmund Fitzgerald".
One device, it gives me the ship. The other device, it gives me the person. I can copy/paste the answers here, if we want to compare.
Again, this could happen because I used "too hard" of a question. But I'm definitely getting 2 different answers.
You can of course, do this will almost every LLM. I can ask copilot 3 times and get conflicting answers each time.
Maybe for some types of questions that's beneficial. But for simple "what is X" questions, it's not as useful.
