Humanity’s computing energy has doubled each one to 2 years for the reason that Nineteen Sixties, resulting in developments in synthetic intelligence that might deal with main technological limitations.

The idea of the “Nice Filter” means that civilizations face existential threats, resembling nuclear warfare and local weather change, which can stop them from advancing to larger ranges of technological growth.

A Sort 0 civilization, like humanity in the present day, consumes roughly 10^13 watts of power, whereas a Sort I civilization requires not less than 10^16 watts, achievable inside the subsequent 100-300 years if the Nice Filter is overcome.

Sort 2 civilizations, able to harnessing 10^26 watts of power, may emerge in about 3200 years, doubtlessly using constructions like Dyson Spheres to seize power from stars.

Sort 3 civilizations, which may harness power from stars throughout the galaxy, might take as much as 5800 years to develop, with the potential for instantaneous journey utilizing wormholes.

Superior civilizations past Sort 3, resembling Sort 4 and Sort 5, would manipulate galaxies and discover multiverses, whereas Sort 6 civilizations may exist in larger dimensions, transcending present bodily legal guidelines.

The seek for extraterrestrial intelligence stays difficult, with no confirmed indicators of Sort 1 or Sort 2 civilizations detected, regardless of the existence of doubtless liveable exoplanets in our galaxy.
