People were about to face a grand plan that would stretch across thousands of years, and even though life spans had increased considerably, this massive project could not be completed by one or two generations. They would face considerable risks, including both internal and external dangers, and failure along the way was not out of the question.
While there were many avid supporters in society, some deeply worried about the future fate of the new humans.
Indeed, the new human group represented the most radical direction of human civilization... but if the plan truly failed, the entire civilization would still struggle to cope!
These people were scattered throughout society, including some well-known experts and scholars.
From a purely utilitarian standpoint, at this time, one needed a bit of ideological support to sustain oneself, something that other human civilizations did not have, something unique to us.
