While AI searches tend to be much improved over previous generations, I still get some weird stuff.
To the question - how many times did the Nats make the playoffs with Dave Martinez as manager, I got:
So put that in your Sunshine thread. 
Unfortunately, it's a safe bet those searches are going to start getting worse. We've reached a point where the number of AI generated pages has massively increased, which creates a poisoned pool for it to pull from. An example is a search I just saw for famous haiku. The results showed two or three real haiku from respected links and 7 results that came from AI generated lists of famous haiku, which essentially took the first three actual ones and recombined the lines randomly to form new ones. They all kept the 5-7-5 rule, made zero sense, and came from pages with names like '10 Haiku everyone should know,' 'Beautiful Haiku,' 'Haiku to make you think.' etc.
We're rapidly approaching the point where it's not just a case of AI ingesting crappy or spurious results and making things up, but rather it eating its own poop, vomiting it up, and going back for seconds. Short of the various AI makers creating a collaborative standard or maker's mark to say 'this is AI gen content, do not use me in your models or results,' I don't know how they prevent it. Someone will figure out a method at some point and it'll improve again for a time, but this cycle is going to repeat, a lot.
