Saying that things weren’t supposed to go this way is, you must know, a copout at best. So why not just fess up and say that everything is going according to plan.

“Sorry, bud,” you might say, “you were just born into membership of an outdated lifeform. You’re basically a simple, harmless housecat compared to our new AI overlords. But that’s not so bad, is it? You like cats, right, champ?”
All kids like cats. At least, many do. Some prefer dogs. Others prefer to torture animals and, as fate would have it, these kids in particular are about to see what it’s like to be scrawny, helpless, and subject to the possibly malicious whims of a superior being.
