I use AI every day and have unlimited budget. I will certainly not trust it to write safe, system level code for our systems. You absolutely do need to be playing blindfold chess and you can’t do that if the other actor doesn’t tell you the moves it made. Using LLMs as described here is essentially what vibe coding is all about. To use this chess analogy, the model says “checkmate!” and you just believe it because you never heard or looked at the moves it claimed to have made.
