Do Programmers Still Need Systematic Book Learning in the AI Era?

Topic Background

In the AI era, the author notes that relying solely on the Feynman technique for patchy learning often leads to superficial understanding, prompting a question from a colleague at Tencent about the necessity of systematic study when entering new fields or learning new programming languages.

Engineers' Views

01 – miao (Backend Development)

AI tools are valuable, but without a solid theoretical foundation programmers risk losing depth; the optimal strategy is to use books to build a knowledge skeleton, fill details with AI, and reinforce with project practice.

02 – zhicheng (Backend Development)

Using AI presupposes knowing what is correct or being able to falsify hypotheses.

03 – csquare (Backend Development)

One should start by asking the core question: "What do I, as a programmer, truly want to achieve?" Then explore concrete problems, such as performance issues or building AI tools, to drive learning of underlying principles.

04 – spring (Application Research)

Books construct a knowledge system; in fast‑moving AI times, the latest advances often appear only in papers, so reading recent papers is necessary.

05 – silvert (Client Development)

Knowledge should revolve around personal relevance; learning for its own sake is meaningless, whereas learning to solve real problems adds value.

06 – shin (Frontend Development)

AI can enhance what you already know, but it cannot teach you what you don’t know.

07 – cxk (R&D)

In the AI era, programmers still need systematic book study, but the approach must adapt: classic books provide structured, deep knowledge especially in algorithms and system design, while AI can accelerate learning of tools and rapid‑iteration technologies.

08 – alex (Sales)

Systematic study remains necessary; AI assists coding, yet books solidify foundational theory, deep thinking, and architectural skills that AI cannot replace.

Overall, the consensus is that systematic book learning remains important, but should be complemented by AI‑driven practice to stay competitive.
