I've programmed for 30 years so I'm probably mentally locked into thinking about the code underneath it all. But I never understood the details of the electrons moving around in the computer, and it took a long time to even consider what happened as my code trickled down the compiler/JIT, into the OS, down to the CPU.
I don't think it's productive to tell students today they must spend all their time understanding the code. Because it's clear now so many people will bypass that, even myself included. Some of the most fun I have with software these days is figuring out how to make it without looking at the code (for now on side projects only, see below).
I agree we're not quite all the way there yet to do this with large production systems. Yes, LLMs are highly fuzzy and non-deterministic things, but so are electrons! As computers improved we handled random bit flips that would occur due to a large number of unpredictable reasons. In either case, we have to reach a high enough confidence and redundancy bar that it doesn't hinder our productivity.
Raising confidence and redundancy in code output from LLM is still a nascent field. We're learning some things like "maybe unit tests don't work as well for LLMs as they did for humans", and "if the AI can self-evaluate in a loop against a factual number, it does a lot better".
But yeah, in this rapid wave of change I would consider "write the code yourself" more and more similar to "know how your CPU does branch prediction so your loops perform better", and the majority of our efforts will need to go into raising our confidence in this new fuzzy shape of software.
