Some additional detail on what I mean by "most important century"

Abstract

The current century may be the most important in human history due to the potential development of transformative artificial intelligence (AI), such as a system capable of creating advanced digital people. Such AI could lead to a future in which humans are no longer the main force in world events, potentially resulting in a civilization that expands across the galaxy. The author argues that this development, if successful, could create a highly stable civilization with “locked in” values that persist for billions of years, making this century the most important for all intelligent life in the galaxy. The author also acknowledges that the “most important century” concept could be relative to different species and time periods, emphasizing the significance of the current era’s potential to influence the future of all intelligent life. – AI-generated abstract.
