There's considerably more conceptual distance between "dalle but 3d" and "dalle but emits practical product designs rather than concept art" than there is between dalle and 3d dalle.
Conversely, there's considerably more difference in concept and capacity between Dalle, and what's in development but not yet released. Safe to say that OAI and the rest of bigtech is at least a few years ahead internally and the open source community is catching up faster than most think, and even branching and exceeding capabilities in some directions as the tech begins to snowball.
How much money are you willing to bet that there would be an AI producing working clothing designs from prompts in 1 year? If it's less than your yearly salary, even you don't believe this crap.
