I think the article is about the first version, not about reuse. But I could be wrong. But in any case, code is difficult: it requires deep attention, good memory - both short and long term(and long term memory doesn't work so well if you don't exercise the knowledge repeatedly ),good learning capabilities, and good abstractions capabilities. Visual systems are fundamentally easier. So if they can scale well to the required level of complexity and offer similar or better levels of productivity , they may become the 'easy' route.
