they, in fact, will have some understanding
These models have spontaneously acquired a concept of things like perspective, scale and lighting, which you can argue is already an understanding of 3D space.
What they do not have (and IMO won't ever have) is consciousness. The fact we have created machines that have understanding of the universe without consciousness is very interesting to me. It's very illuminating on the subject of what consciousness is, by providing a new example of what it is not.
You're not being naive, the comment was joking about the meme incorrectly using "starring" (the gerund of "to star" as in "Cillian Murphy is starring in this movie") when the meme creator clearly meant to use "staring", the gerund of "to stare".
