After using AI for so long, the deepest feeling is not how many words it can help you write or how much code it can generate.

The most underestimated ability of AI is that it can enable an ordinary person, in just one afternoon, to build a knowledge structure in their mind that would normally take years to accumulate.
This era is not lacking in knowledge, nor is it lacking in information.
Today’s tool, tomorrow’s case study, the day after tomorrow’s new model— all are fragments.
And no matter how many fragments there are, they cannot form cognition.
Don’t treat tools like Codex as a question-and-answer search box; see it as an industry researcher who doesn’t need a salary or get tired.
When entering any new field, it can help you quickly establish an industry map, break it down into first, second, and third-level directories, draw it as a tree, and then form a network.
The truly valuable thing is this network, which is a structured web of scattered knowledge, forming a complete system.
