Walking the Walk
One problem is, it is much too easy for someone to bullshit about longevity and intelligence. Durk Pearson and Sandy Shaw have made a good living bull-shitting ever since the 1980s. I met them once and spoke with them briefly. It did not take long for my bullshit detector to go off. They attempted to come across as bio-medical experts, but I was the one who was in medical and graduate schools at the time. They failed the test, they simply did not know what they were talking about. Good enough on a surface level to snow-job the uninformed. Not good enough to back it up.
Preparation for next level humans is too important, too complex, to be left to pretenders and bullshitters. Those types of people may well dominate the interaction with popular media, and that is fine. Consider it a smokescreen of sorts to help conceal the actual work behind the scenes.
Next level humans will be incredibly intelligent, intelligent enough to know how to augment their own intelligence. Time will be a constraint, even for someone with a lifespan of 500 years. Priorities will be set, critical paths laid out, redundancy and rapid adaptability built into the system. No one can really anticipate what it will mean to have an IQ three times normal combined with a several century lifespan.
When next levels are ready to begin walking the walk, they will need guidance, in the same sense that a space ship needs guidance. The dangers are great and numerous and need to be mapped out. Someone has to prepare the way. This is part of the work that needs to be done, along with the nuts and bolts of combining longevity advances with intelligence improvements and emotional balancing/wisdom generation. Long life and intelligence would be a curse without emotional balance and wisdom. All of the above together would be less than fulfilling without tangible guidance and direction.
We cannot any of us know everything. Some of us compulsively try to do so. The best we can accomplish will be very little beside the accomplishments of a next level. All the more reason for the compulsives to do everything in their power to bring the possibilities to reality while there is time for them.
