I don't particularly dislike Emmett, their "feral demon-spawn masquerading as a person in a hoodie" gimmick is kinda fun. I wish Jeph would decide if they're 14 years old or 8 years old though, the 'owo so cuute' thing was wearing very, very thin when we first did it ~6 years ago with Marigold, and Sam, and probably several other infantalised adults.
From what we've seen of QC's AIs, this would probably qualify as a 'human experience', like cashing a cheque or going to the coffee shop. It doesn't have inherent physical value for them, but it would create a situation where they would have to make monthly visits to 'the hairdresser' and get their tail 'styled' according to occasions or fashion.
Y'know, all the stuff that real-life internet perverts would like to do, given the option.
