I first realized that catpeople were a potential threat, at the point when a friend said - quotes not verbatim -

“I want to spend a million years having sex with catgirls after the Singularity.”

I replied,

“No, you don’t.”

He said, “Yes I do.”

I said, “No you don’t. You’d get bored.”

He said, “Well, then I’d just modify my brain not to get bored -“

And I said: “AAAAIIIIIIEEEEEEEEE”
