I think you're speaking in the hypothetical.
The original version of GitHub Copilot was the "spicy autocomplete" idea of just filling in a line or a few lines. I didn't use it even then, because the copyright situation was absurd. I figured MS would fix all that, improve quality by *narrowing* scope, and then *maybe* it would be a decent tool.
Instead, we ended up with the world of Claude Code et al. Prompting "build me a thing" and then getting a huge PR is not autocomplete. It's slop.
