And that's exactly the same for coding!

Coding is like writing documentation for the computer to read. It is common to say that you should write documentation any idiot can understand, and compared to people, computers really are idiots that do exactly as you say with a complete lack of common sense. Computers understand nothing, so all the understanding has to come from the programmer, which is his actual job.

Just because LLMs can produce grammatically correct sentences doesn't mean they can write proper documentation. In the same way, just because they are able to produce code that compiles doesn't mean they can write the program the user needs.

I like to think of coding as gathering knowledge about some problem domain. All that a team learns about the problem becomes encoded in the changes to the program source. Program is only manifestation of the humans minds. Now, if programmers are largely replaced with LLMs, the team is no longer gathering the knowledge, there is no intelligent entity whose understanding of the problem increases with time, who can help drive future changes, make good business decisions.
