I think a lot of people have a fear of AI coding because they're worried that we will move from a world where nobody understands how the whole system works, to a world where nobody knows how any of it works.

This comment on the article sums it up for me, at least in part:

“Nobody knows how the whole system works, but at least everybody should know the part of the system they are contributing to.

Being an engineer I am used to be expert of the very layer of the stack I work on, knowing something of the adjacent layers, mostly ignoring how the rest work.

Now that LLMs write my very code, what is the part that I’m supposed to master? I think the table is still shifting and everybody is failing to grasp where it will stabilize. Analogies with past shifts aren’t helping either.‘

A valid concern.
