As mentioned elsewhere (I'm the author of this blogpost), I'm a heavy LLM user myself, use it everyday as a tool, get lots of benefits from it. It's not a "hit post" on using LLM tools for development, it's a post about Cursor making grand claims without being able to back them up.
No one is hung up on the quality, but there is a ground fact if something "compiles" or "doesnt". No one is gonna claim a software project was successful if the end artifact doesn't compile.
