The essential complexity in today's coding is that code is created by humans. Therefore humans, we have to understand existing code bases to modify them and this is non-trivial. We also have to understand "what" needs to be built, that is the infamous "requirements". I think eventually coding will be automated away with artificial intelligence. I did not think like this for a long time in my career (that programming will be automated I mean) but neither I thought that computers would be able to create "deep fakes" and things like understanding & speaking human languages.
