In a sense yes. I trust that my coworkers will be accountable for their outcomes and accomplish them with the high quality bar I know they intrinsically hold themselves to. And that they understand our shared goals and if they don't, they will work to become aligned.
And if I can't say that for a coworker, well, that's performance feedback.
Highly likely, your trust is just based on your feelings, and they don't do much for the product quality.
Your coworkers are if anything less reliably deterministic than an AI. And the human version of a prompt injection is called social engineering and it’s far more of an issue than actual prompt injection and has been for an extremely long time.
