Stable Diffusion is about closed to open.
Copilot is about open to closed.
The Stable Diffusion version of Copilot would be something like
"Give me a cart checkout algorithm in the style of Carmack, secure C style."
And that's fine, if the destination code license were just as open--or even less restricting--than the source codes' license (relicensing rules permitting).
What could be the issue is the generated source becomes even more closed or proprietary, which defeats the original source intent.
Is that right?
