The Precipice notes

• "If we are the only moral agents that will ever arise in our universe—the only beings capable of making choices on the grounds of what is right and wrong—then responsibility for the history of the universe is entirely on us. This is the only chance ever to shape the universe toward what is right, what is just, what is best for all. If we fail, then the potential not just of humanity, but of all moral action, will have been irrevocably squandered." -- it sounds like Toby is still a moral realist. Does this mean that he would expect aliens to also discover moral truths, so that as long as some civilization spreads to the stars, it's ok if humans go extinct (for non-AI extinctions)?
