Getting back to this....

  The most effective response is rarely to argue the general case. Instead, acknowledge the concern, offer a brief reframe, and propose one concrete demonstration on the person’s own code. Most concerns are resolved by a single successful experience.

Part of the reason LLMs have led me to tear out so much of my own hair is how many people seem to have made it through four years of STEM college without developing any scientific thinking ability whatsoever. A truly stunning number of people have been wowed by "a single successful experience." Actually that section is full of horrible logic:

  Concern
  "I am faster without it."

  Suggested response
  That is likely true for code the person writes routinely. Suggest trying it on the work they tend to avoid: legacy files, unfamiliar services, or test scaffolding, where the leverage is highest.

  Evidence to offer
  Time one tedious task both ways and compare.
