"Coding" is just a poor term for this, as there's so much room to weasel different meanings out of it. At every company I've worked in past 20+ years the "coders" were engineering a product from wrong or unclear requirements and specs from non-technical people. The act of coding was secondary (but an important throttling function to make us stop and think about what is even possible or makes sense.) Never did FAANGs, so YMMV.

Really doubt we are near that being solved with non-technical folks + LLMs. I'm seeing people gleefully rebuilding products with the exact same blind spots in their understanding/logic using LLMs. Claude, etc are not seemingly able to "AGI" around goofy asks. The CSS looks a little nicer than their legacy products though, lol.
