A lovely and optimistic peace of mind-thought PlaneCrazy and I have little doubt that much of your prediction will manifest itself and possibly within the foreseeable future (for some).

I doubt if survival is due solely or mainly to our intelligence and I do accept that adaptation comes across strongly but, there is a feature that is almost unnoticeable yet is evident in human kind and may not exist in other species; it is the phenomenon of each generation having to re-invent itself. We see this evidence in the young who perpetually reject the values of their parents and earlier generations and it is this regeneration of thought precesses that seems to push humanity towards some yet unknown future.

I readily accept that we may wish to live longer but in that same desire will exist the seeds of destruction.

I enjoyed your postings; quite refreshing to have something to agitate the grey-matter.
