Ben Goertzel has written a Cosmist Manifesto which I consider as a seminal document, and recommend to everyone. He has included a short summary on Ten Cosmist Convictions based on an earlier draft of mine which was discussed on the Cosmic Engineers mailing list. Needless to say, Ben's edits, which include many improvements to 1-7 and the new points 8-10, have made my original draft much better. Thanks Ben!
1) Humans will merge with technology, to a rapidly increasing extent. This is a new phase of the evolution of our species, just picking up speed about now. The divide between natural and artificial will blur, then disappear. Some of us will continue to be humans, but with a radically expanded and always growing range of available options, and radically increased diversity and complexity. Others will grow into new forms of intelligence far beyond the human domain.
2) We will develop sentient AI and mind uploading technology. Mind uploading technology will permit an indefinite lifespan to those who choose to leave biology behind and upload. Some uploaded humans will choose to merge with each other and with AIs. This will require reformulations of current notions of self, but we will be able to cope.
3) We will spread to the stars and roam the universe. We will meet and merge with other species out there. We may roam to other dimensions of existence as well, beyond the ones of which we're currently aware.
4) We will develop interoperable synthetic realities (virtual worlds) able to support sentience. Some uploads will choose to live in virtual worlds. The divide between physical and synthetic realities will blur, then disappear.
5) We will develop spacetime engineering and scientific "future magic" much beyond our current understanding and imagination.
6) Spacetime engineering and future magic will permit achieving, by scientific means, most of the promises of religions -- and many amazing things that no human religion ever dreamed. Eventually we will be able to resurrect the dead by "copying them to the future".
7) Intelligent life will become the main factor in the evolution of the cosmos, and steer it toward an intended path.
8) Radical technological advances will reduce material scarcity drastically, so that abundances of wealth, growth and experience will be available to all minds who so desire. New systems of self-regulation will emerge to mitigate the possibility of mind-creation running amok and exhausting the ample resources of the cosmos.
9) New ethical systems will emerge, based on principles including the spread of joy, growth and freedom through the universe, as well as new principles we cannot yet imagine.
10) All these changes will fundamentally improve the subjective and social experience of humans and our creations and successors, leading to states of individual and shared awareness possessing depth, breadth and wonder far beyond that accessible to "legacy humans".
A clarification: in my draft, "will" is not used in the sense of inevitability, but in the sense of intention: we want to do this, we are confident that we can do it, and we will do our fucking best to do it.
