I agree - we should use the tools. But we should be mindful about how humans actually learn.

Some improvement ideas:

A prototype can help in the “Better communicate the idea/feature” part but it is even better if you let engineers do this as learning by doing is better than just being shown the result.

Vibe coding doesn’t help in “Understand the systems” - on the contrary, this is already a well known fact that vibecoding has negative effect in understanding the underlying system. It should be hardboiled documentation reading, trial and error which helps, otherwise you get only the illusion of competence.
