I'm really fascinated by all the tools the OS community is building based on StableDiffusion (like OP's), which compares favourably with the latest closed-source models like Dall-E or Midjourney, and can run reasonably well on a high-end home computer or a very reasonably-sized cloud instance. For language models, it seems the requirements are substantially higher, and it's hard to match the latest GPT versions in terms of quality.
* The amount of times that I've seem an 'impressive' selections of AI images that I consider a critical failure deserves it's own word. The AIs are impressive for even getting that far, it's just that some people have bad taste and pick the bad outputs.
Yes, it's true that not all technology evolves as fast as predicted (by some, at some point), but first of all I still believe we will see self driving cars in the future and secondly, it's one anti-example in a forest of examples of tech that evolves beyond anyone's expectations. I don't find it very convincing.
We might need to create real intelligence for that to become true. A machine that can think and is aware of its purpose.
