Beautiful analog
An extreme example of the distinction between analog and digital that I'm hammering this week.
Via Science Daily, a closeup look at how jellyfish use water vortices for propulsion. Human engineers have figured out some of these concepts in designing aircraft and automobiles and submarines, but those machines have hard surfaces.
Unlike bilateral animals from tardigrades to mammals, jellyfish have a decentralized nervous system with no central brain and no separated efferent and afferent channels. They have muscles everywhere and senses everywhere. Total infinite-directional signals and feedback everywhere.
The whole system works for a PURPOSE, constantly shaping the everywhere-muscles to propel the jellyfish in its chosen direction with a chosen rhythm. The edges of the bell create vortices where needed to lower or raise water pressure at that point, just as an airplane wing creates vortices to raise pressure or a hail cannon creates vortices to break up pressure in the clouds.
Where is the PURPOSE if not in a cerebellum driven by a hippocampus? We don't know. It's everywhere.
LIFE IS PURPOSE.
