What common pitfall results from merely copying code without internalizing the long-term learning necessary for actual problem-solving?

Tutorial hell.

Tutorial hell is a state commonly encountered during self-study where an individual meticulously follows step-by-step instructions in tutorials or courses, resulting in the successful replication of code examples, but without developing the underlying conceptual understanding required for true problem-solving. This process leads to dependence on guided instruction rather than building the internal mental models necessary to debug novel issues or architect new solutions independently. To move beyond this state, especially in development roles, professionals must actively create original projects that force them to engage with industry standards and technical challenges outside the scope of a pre-written guide.
