No, they're definitely the reverse. They're "the singularity." Most obviously clear in Grok's which is a literal pictogram of a black hole. But these are entities that suck things up, not produce things.
The mental model of the superintelligence, to a true believer, is much more like a thing that consumes our world (hopefully for the better) rather than a thing that exists within the world and "produces stuff" in it.
Claude’s logo is closer to a dandelion than an aperture (though closer to a butthole than either)
