Yes, LLM is a tool. And CEOs of the tech companies are retaining developers not because there is value in writing code by hand, it's because developers can use that tool effectively and responsibly: they can tell bad code from good code, they design the solution, let AI do the hard boring work of coding it out, then these developers check its output, test it, also they can be creative and e.g. ask LLM to review LLM's output, etc etc.

But the need to manually type stuff out arises very infrequently in my experience. It happens but it's an exception, not the rule.
