"Visual tools don't teach you to code, they introduce an unnecessary layer" I disagree. The main benefit of a visual tool (if implemented correctly) is that it exposes the constraints and the tool grammar to the user when implementing and not only when compiling. The difference is more or less of that with clay, and lego blocks. Yes, you can design a house with both (Lego house). Clay offers an infinite shape grammar, but if all you want is a lego house, then Lego blocks are much faster. Now, is the visual tool a cognitive crutch, or a bicycle for the mind, is another matter entirely.
