A junior developer used to wait days for mentor feedback. Now that loop closes in seconds.
This is not a small change.
When feedback is scarce, you batch your questions. You guess. You move on and hope. The gaps between learning moments stretch long. Mistakes harden into habits before anyone notices.
When feedback is abundant, learning becomes continuous. Small corrections compound. The rhythm shifts from episodic to constant.
We designed most learning systems around scarcity. Scarce experts. Scarce attention. Scarce time. AI changes the supply side.
