I can confirm. I am somewhat optimistic though. I have just finished using a 100% vibe-coded app that I needed in a hurry. It ran for a month without major incident, but man there are a thousand little bugs that I didn't dare ask it to fix, because that code was already mangled beyond my comprehension and everytime I asked for a fix it doubled the complexity of the code.

"Thank you for informing me of the actual structure of the config file, I have made that the default and have kept my original work as an optional format then added code to detect whether you chose to use your preferred format or mine."

I have started a complete human rewrite for next year so I can figure why it dead simple things, like getting a color value from the config only works sometimes.

Much. My point is partly tongue in cheek, but one found that "one-shotting" is still hit and miss. I'll see am impressive outcome from the first prompt, but the last 20% takes hours to refine.
