To me it seems it happened the other way around: a reduction in the valuation of mastery preceded, and facilitated, the acceptance of LLM output as "good enough".

What was called "move fast and break things", is one example. This development model leaves behind a trail of shit, that is poorly integrated and often, fully understood by no one.

Like vibe coding, this is all great until something doesn't work (not IF something doesn't work, but UNTIL).

This failure to appreciate mastery is illustrated in even earlier "business model" strategies, such as elimination of large corporate R&D laboratories, and the LBO raiders.

It's widely understood that every product and service in the current era is going to shit (certainly for the users, even if not for the ownership). Toasters built in the early '50s still work, toasters built today are designed for the dump. This isn't a problem with toasters, it's a problem with the business model of unrestrained capitalism.
