IME companies hire an ethics team to say they have an ethics team. The ethics team has no sway, no influence, and will never be able to move the business. They will try, and they will make reasonable recommendations, but the company will say, "that costs money..." and not take them.

OpenAI was probably able to at least pretend that her role mattered... until they let their AI autonomously hack a rival company, then used the incident to score marketing points. I'm not surprised she left.

If you ever feel like your job is useless, remember that raytheon has an ethics team.

Scapegoat team (when working for an obviously unethical company).
