At the end, we envisioned the ethics review board as an independent organization which oversees multiple AI-developing companies:
➤ The board supports the companies in building internal channels for voicing and responding to ethical concerns
➤ The board can receive reports about ethical concerns regarding the companies it oversees from employees, consumers, activists, and any other stakeholder
➤ The board has the power to reward and penalize the companies it oversees, e.g., in the form of positive and negative PR
➤ The board has the power to protect those who report ethical concerns
➤ The board provides resources to help stakeholders understand AI ethics issues
The main ingredient for a board like this to exist is a few companies that are interested in participating!
