I have noticed similar phenomena with Claude, where its vocabulary subtly shifts how I think/frame/write about things or points me to subtle gaps in my own understanding. And I also usually come around to understand that it's often not arbitrary. But I do think some confirmation bias is at play: when it tries to shift me into the wrong directions repeatedly, I learn how to make it stop doing that.

It definitely adds a layer of cognitive load, in wrangling/shepherding/accomodating/accepting the unpredictable personalities and stochastic behaviors of the agents. It has strong default behaviors for certain small tasks, and where humans would eventually habituate prescribed procedures/requirements, the LLM's never really internalize my preferences. In that way, they are more like contractors than employees.
