"A junior engineer who has only ever used LLMs to write code and create architectures does not just not have that experience but also won't acquire it."

My ego tends to agree, that how can they be ever competent, if they have not endured the same hardships as I had crunching trough problems and getting allmost lost in the details.

But I rather suspect, they will turn out fine. I know LLMs are great for me to learn and I think the young generation will learn what they need to learn to get the job done.
