There is no "problem".

The architecture and the intent don't matter to business folks, it never has, and with LLMs it matters less than ever.

Vibe code into production is satisfactory regardless of architectural understanding or intent. If there are issues, just have the LLM spin up some agents to play whackamole until the issues are pushed beyond visibility.

Ultimately, the idea that we can hang onto fleeting engineering disciplines misunderstands where the industry is going, regardless of any assessment of the LLMs capabilities.
