I don't think the majority of humanity will ever accept "AI" as being anything more than a fancy computer, let alone a 'new species', even if it was proven sentient.
You just need to embody the AI in something that moves, and then people will definitely treat it as a new species. Already happening in my town with delivery robots: when they get stuck on a kerb, a person will stop and help them up the kerb while saying soothing words like to a pet: “There you go, little guy, now everything is alright.”
