I'm sure we'll have vibed infrastructure and slow infrastructure, and one of them will burn down more frequently. Only time will tell who survives the onslaught and who gets dropped, but I personally won't be making any bets on slow infrastructure.
As a trivial example I just found a piece of irrelevant crap in some code I generated a couple of weeks ago. It worked in the simple cases which is why I never spotted it but would have had some weird effects in more complicated ones. It was my prompting that didn't explain well enough perhaps but how was I to know I failed without reading the code?
