This, to me, is the biggest differentiator. In terms of results, there's a huge yawning chasm between the person who says "Claude make me a $thing" versus the person who puts in the effort to lay down the overall architecture, gives some thoughts to libraries and dependencies, performance trade-offs etc, and only then begins prompting.

Knowing how to implement Djikstra or a linked list by heart is no longer important. Actual software engineering skills are more important than ever.
