I saw it, I was excited, then the disappointment hit me.

One day a human will make something like this and I can use it.

Why do you think so?

Not really. Tests, architecture documents, commit messages, changelog and various boilerplate like data model classes or styles benefited from AI tools (it'd take years otherwise for a single developer to build a product like this). But the core functionalities have been hand-coded, if you exclude the occasional Copilot/Windsurf autocompletion.
