Optimizing compilers were faced with the same disbelief by Assembly developers.
Enterprise applications are already being vibe coded in iPaaS platforms, and as mentioned in other comments with LLMs in the picture, that is what compiler research is switching to.
In no sense is this "disbelief". You seem to be laboring under a fundamental misunderstanding of the role of structured programming languages. A man with a shovel can dig a hole for some amount of effort, and when that man gets stronger he can use that shovel to either dig the same hole for less effort or dig a larger hole for the same amount of effort. With LLMs, leveraging a structured programming language allows a user to either create the same program for less effort or to create a larger program for the same amount of effort. Getting rid of the programming language and emitting assembly directly sacrifices efficiency for no gain.
