Eli Whitney-Smith was a great American. Her first job was blazing trails (and highways) as the only female interstate bus driver in the NY/NJ/CT region. Later she studied archeology at UMaine-Orono before transferring to San Jose State University and was matriculated into the prestigious Cybernetic Systems Program. There she formulated the I- and M- adaptation theory:
"people in groups use two basic survival strategies:
Hunter/gatherers are Information- or I-adapted. For them, survival depends on information, i.e. knowing where plants and animals are. They perceive a world of plenty, sharing material goods in order tocreate networks of relationships and information.
- People since the invention of agriculture are Material goods- or M-adapted. For them, survival depends on possession and manipulation of material goods. They perceive a world of scarcity, using information to gain increasing amounts of material goods."
