I propose the goal should be to aim to maximise overall human wellbeing (current and future), with particular emphasis on minimising harm, drawing on the Benthamite principle from the Enlightenment ("greatest happiness of the greatest number") but with care weighting to ensure "average wellbeing" avoids compromising the welfare of a particular minority, as laid out by Richard Layard in "Happiness: lessons from a new science (2nd edition)". Or you could replace human wellbeing with "wellbeing of sentient beings" in the way Sam Harris does in the Moral Landscape

Physics should be goal. Learning and solving for the rest of immutable laws in physics.
