Well that's a new experience, I naively googled for "Fur svtherf bhg gung gurl gnyx nobhg crbcyr nf bowrpgf gb or bjarq" and gemini responded to the text without rot13ing it, so I had no idea why it was telling me what it told me, I had to decode it to make sense of it's answer

I pasted it into Kagi and the smart response just showed the clear text. Usually the smart responses are much more verbose.
Just read "a deepness in the sky" last month, surprised to see a reference here.
I had forgotten that section. Time to reread, I guess!
