Never impress a parent/teacher?
If they made it the old way, without LLMs, I guarantee most parents/teachers who have real (pre-2025) programming experience will still be impressed.
Are kids doing photography also not impressive because smartphone cameras all default to full-auto, computational processed modes? Obviously not. You can still stand out just by giving more effort and being more detail-oriented. The average smartphone photo taker doesn't even know how to utilize focal lengths effectively.
You're in a bubble. Go look at what actual kids are doing. Only the actually extemely motivated/smart ones are generating playable full-multiplayer games from raw code (AKA not in another game's sandbox); even with claude/codex.
