I'm from 2283, I have no way to prove this that you would understand. Multiple time travellers have come to this time, yet you haven't listened. They get kidnapped and never respond. In 2283, we are part of a universal coalition of species, peace is overwhelming and dominant. In 2022, an alien species will make contact and tell you to form into a one government country. You will not listen. They will come and force you to do so. Many lives will perish, but in the end life will be better. The secret to infinite power will be discovered, every single person on the planet WILL be fed, clothed and housed, and going to another star system will become a family holiday, rather than a multi generational achievement of science and physics. in 2016 you will discover the remnants of a dyson swarm around a star 1500 light years away. This will prove to be nothing.

Listen or perish, it's your choice.
