Also validates GIGO (Garbage In/Garbage Out) ... Grok had garbage data resources for your question as you discovered until you pointed it to valid data.
Also funny that you had to "argue" with it like that. I've not experienced that with Grok yet though most of what I use it for is data analysis and I give it the data to analyze.
I've read similar stories like yours though, so I believe you it happened.
It wasn’t me, but another poster.
But in light of SO many companies going “all in” on AI (on the wishful greed that they can replace all humans), I’m getting ready to short certain stocks or buy put options on them.
