I understand that advances in space science are the only way our species survives past the next 1000 years, truly I do. But look...
...there is an even more crucially critical area we need to advance in before anything else is even worth looking at, and that area is the science of human harmony.
We waste so much resource on conflict and greed; if we cannot learn how to live together and be productive without persecution, rampant consumerism turning people into commodities, and without dominance hierarchies, our species is going to die on this rock sometime relatively soon after the year 3000.
If we don't drop everything and focus on human harmony all the scientific advancements we have made up to this point, and will make in the future up until the end, will have meant absolutely nothing because there will be no one left to advance any further or to even remember what we did achieve.
It will be as if we never existed at all.
