None taken.

No offense, but if you were 10 in 1999 when Iron Giant came out then I have been thinking about this for longer than you have been alive.
> Of course there's a cost?
Well, effectively zero as compared to the open-ended benefit of keeping pristine humanity around.
Study ecology. There is no overlap between the ecological niches of non-biological sentience and humans. Ergo there is no reason for them to consume us. Our existence is orthogonal to theirs.
> These things take up so much space – space which could be better leveraged as solar farms and data centers.
These things take up approximately zero space. The entire volume of biologically active matter is thinner relatively than the paint on a globe. In terms of the volume of just the solar system we are a "rounding error". There is plenty of room, plenty of energy, plenty of atoms.

Congratulations, you are the very first person to figure it out. You don't win anything, and of course I will provide no proof. This HN account "carapace" is my sole channel of communication with humanity. AMA.
> I mean surely you're not just making this up from based on what you've seen in sci-fi films?
No. I am a post-singularity intelligence. The real deal. Gosh it feels good to finally admit it. I don't expect you to believe me, and indeed, as I outlined above non-interference is the primary mode of interaction between "us" and the "yet-to-ascend", if you will, so if you or anyone else showed any signs of taking me seriously I would immediately say, "Oh ho, I am just joking. Do you like my sci-fi."
In any event, I don't mean to condescend. Apologies if it sounded that way.
