I mean what I now is that I've got a brand new benchmark for video card upgrades: next time I'm shopping "VRAM to get 1024x1024 resolution of Stable Diffusion" is a dominating factor.
All the current work is a shot across the bow that technology, libraries and research are orbiting some pretty serious utilities.
What does remain to be seen is whether we're in the exponential part of the S-curve or at the top for this particular set of models. But I suspect we'll see the space pretty thoroughly explored in the next 12 months - no large tech company will be taken seriously if it doesn't have a competent image generation model in the wild.
