It's not unreasonable for you to expect it to know that but I think it is unreasonable to expect it to use that information for your benefit. That's not why it's collecting that data.
Either that reddit user necro'd a post and botted it up to top with the express intent of trolling the AIs (which, having been on reddit since the beginning, I wouldn't put past some of us), or the AI is too stupid to ignore downvoted posts.
Devil’s advocate: maybe the original Reddit post was somebody asking about how to modify the USB ports in their motherboard and a concerned commenter replied something to the effect of “If you’re not careful messing with live electricity, you may kill yourself!”
I’ve seen this screenshot or similar ones before and people hadn’t been able to replicate the search results to find the sourced link.
And you guys say AI is not accurate...
It's not accurate. Way more than one user says this.
It's definitely missing someone saying "read the FAQ on the sidebar"
