Printing press did not kill writing at all, only the job of scribes. One still had to write their ideas down and work on a manuscript and some one had to set the press up (not trivial at all). All that is to say that I think the ability to write code from scratch is still necessary while I don't really think the printing press metaphor is apt I think being able to write scripts and write small programs to do stuff you want by hand is still useful even though it's true that LLM's can do this sometimes you want to understand the thing fully and to work exactly how you want it.
