Person A (the maker) has a problem, and works to solve it by creating a tool. The tool is effective and person A applies it to many similar problems to good effect.
Person B (“taker”) has just such a problem and applies the tool. Unfortunately it doesn’t help nearly as much as person A thought it would. A long series of similar people with similar problems come along and fail.
What the “maker” doesn’t realize is that the tool is ineffective unless you also went through the learning process required to build such a tool, which forces you to understand the problem domain far more deeply than a “taker” ever will.
The tool actually hampers the learning process that the maker benefited from, by asking the taker to learn tool semantics instead of spending time on the actual problem.
