There is nothing preventing Junior Developers to develop their own systems and understand it.

In fact, the world is always filled with curious people who like to go one level below.

This hysteria about losing "Junior Software Engineers" -- most of them in it for money, promotion rather than craftmanship, is over-rated.

People who love solving puzzles will always find ways to sharpen their mind.

People who love understanding things, will always find ways (AI will help them tremendously).

People who love taking shortcuts will always find ways for it (AI or not)
