Blender will just add AI creation/editing
That's like saying we'll add internet browsing and YouTube to Lotus 1-2-3 for DOS.
It's weird, legacy software for a dying modality.
Where we're going, we don't need geometry node editing. The diffusion models understand the physics of optics better than our hand-written math. And they can express it across a wide variety of artistic styles that aren't even photoreal.
The future of 3D probably looks like the video game "Tiny Glade" mixed with Midjourney and Google Genie. And since it'll become so much more accessible, I think we'll probably wind up blending the act of creation with the act of consuming. Nothing like Blender.
How well will they do with something like creating two adjacent mirrors with 30 degree angle between them with one of them covered with varying-polarized red tinted checkerboard pattern?
They do a better job of fluid sim than most human efforts to date. And that's just one of thousands of things they do better than our math.
Now I know you're too far down the hype rabbit hole. Either that, or you lack a cursory understanding of diffusion models.
