Reminds me of my recent vibe coding project of porting Winamp AVS to web using Emscripten. It worked so well that it was simply.. done after a few sessions, and I was amazed and also feeling fuzzy in the head.

One turn involved ChatGPT explicitly fixing C++ source code to fix beat detection for the available audio sources after I complained that it was broken.

Hands down, sure, the most respectable work, apart from the original AVS code, was done by the Emscripten contributors. Anyway, it readjusted my expectations, even after my day job switched to agentic coding as the primary development tool.
