I think the argument is that dev with some vibe coding can successfully setup servers that are good enough already for 10x less cost and 95% reliability
Plus that 5% left out is a one in twenty chance that some business critical service may fail when least convenient.
And when it does, the person that vibed it into existence will only have ChatGPT to fall back to, having no personal or organizational experience to rely on.
But they have a 95% chance of getting it right, if they don't panic too much.
