So I'm down with a summer cold that flu in out of the blu. Mum is fairly aged... the combination means suddenly the chores are piling up. Somehow the way my mind works I started to wonder what it would be like to be marooned, and the first person in the world. As the first person, instinct would guide me some - the rest owuld be trial-and-error ... and unless in a Utopian setup there would be little time to think. The second person may be able to get some guidance over-and-above by instinct by watching how the first does things... and so on.
Science & Technology require keen observation. They may also require effort away from actively being involved satisfying basic human needs, and instead focussed towards experimentation which comes with it's own capital cost of resources & time - what may be deemed unproductive pursuit.
The thought in my mind is - is there something like a critical population mass required for science/technology to develop?
