Just for fun I asked ChatGPT "How would you ask an LLM to write a drawing program for the ATARI?" and it asked back a bunch of details to which I answered "I have no idea, just go with the simplest option". It chose the correct graphics mode and BASIC and created the program (which I didn't test).

I still agree with you for large applications but for these simple examples anyone with a basic understanding of vibe coding could wing it.
