We are now, according to this theory, A K0 civilization . A K0 becomes K1 when it survives the discovery of element 92 and the development and maintenance of a chemical industry. Then it starts to work towards a synthesis of all its knowledge. It will be understood that if one nation releases vast quantities of ozone-depleting gases, the entire planet is affected by it. It will see the end of the universe , if there is one.
Nothing known in nature can physically destroy it.
It will probably conceal its electromagnetic signals or scramble their messages across the complete bandwidth and unscramble them at the receiving end. These are small robotic probes that land on the moons of distant planets and build self-replicating factories.
