Curious to know why you think it's vaporware. Are the latest LLMs like 3.5 Sonnet bad at original programming based on your experience? It hasn't been the case for me when using it for real world projects lately.
I hand held it, gave it tests, called out flaws in reasoning.. etc., and it still didn't fix.
The longer the chat the more likely it was Sonnet forgot a clarification I provided.
Overall huge waste of time, lost my train of thought and I was helping an LLM rubber duck and fail repeatedly
