If I tell someone literally "What value do you have if you're just acting as a pipe to the AI?", I'm pretty sure my manager will schedule a quick 1:1 to ask me why I'm telling peers that they have no value.

Your manager should then have a meeting with those coworkers too, or their manager(s). Depending on whether the company's leadership position is "AI at all costs", they may reconsider if they realise blind trust in AI is creating problems.

Schedule the 1:1 first to let your manager know your peers have no value.

Yeah. Plus the sloppers tend to be highly ranked
