So in summary, to plan ahead for the next couple of trillion years or so we need to learn how to manipulate stellar matter to form new stars.. or find other sources of energy like black holes. Seems that if we learn to live off black holes it would buy us some more time to figure things out for now. But all this is just short-term, we better get thinking about creating new universes as well and solving this dark matter thing.
Don't worry, we only just started and considering how far we got so far we are likely playing this on easy mode and can afford a couple of years to goof around every now and then. As long as we don't get overconfident and hit a great filter we should be fine
