It was mostly rethorical, but thanks :)
BTW I think the concrete proper nouns we use (like "Eve") are actually abstractions too and prove some reasoning capability.
At first infants don't realize objects exist. They just see shapes and react to them. When something disappears from their view - it's the same as if it stopped existing. That's why you can play peekaboo with them and not bore them.
To abstract from "a shape that sometimes appears, moves and disappears" to "an object that exists over time even when it's not visible" is a pretty impressive generalization. If AI was able to do it on its own I would be impressed at least. I'd even say it's more impressive than the next step (generalizing from "mom' and "papa" to "person").
Of course we have hardware in our brains dedicated for this stuff and it's probably not conscious reasoning that gets us the object permanence. And we don't remember it in any case. So we take it for granted.
But when you think about it the generalization from "sensations in my eyes" to "objects in the world" is a pretty big one.
