The content on Internet will invariably biased towards the novelty. Between that bias and enormous marketing spin and the most self important people gravitating towards it, it's an expected reality. One that will be applicable to some scenarios.

Content saying that for some situations, the existing methods remain best isn't going to light the world on fire. Also, tech folks tend to be more shy about "not getting" a seemingly great new tech.

In terms of how much it applies to an individual situation, it's too nuanced to really make a universal judgement. But in my local circle where I can grasp the nuance, the teams that have gone all in on deeply agentic are teams that already were kind of crappy.
