Many programmers are not as impactful as they could be because they are looking at the code. Looking at the code is suboptimal and often pointless. The amount of code that LLMs generate makes it impractical to read, understand, and edit every line of code. It's more efficient to just control the ideas - how things work, what is the best design, and how to reach a certain level of performance - and then check the implementation for correctness.
