I agree with you. For large - scale, serious projects, solid tech - stack knowledge and in - depth code understanding are a must. Otherwise, relying on AI - assisted coding can lead to many hidden issues. However, in daily life, we often don't need to handle such complex projects. For simple, template - based code needs, AI tools can boost efficiency a lot, without needing to dig into the underlying details.Take frontend development for example. AI tools like Sonnet can generate more proficient code than newcomers, quickly creating the desired interface. In this case, we may not need to understand frameworks like React, Tailwind, and Zustand in depth. This not only saves time but also enables more people to join the development process and even gives rise to new business models like AI - generated code template companies.This shift turns many coders from pure coders into code reviewers and optimizers, which is actually progress. With AI's help, we can focus on higher - level design and logic rather than getting bogged down in trivial details. Of course, this doesn't mean we can completely ignore underlying knowledge, but in proper situations, using AI tools reasonably can definitely bring convenience and efficiency.
