Much like the difference between the linear processing used
by a computer and the, let’s say ‘holographic’ thought process of the human
brain, which has kept computers from out ‘thinking’, read that as processing if
you like, us and kept us from having to recognize robots and their computer
brains as anything close to human. The Aliens
that have the ability to get to Earth have no reason to recognize us until we
get our physics together. We know a lot
about our physical world but a unified theory of physics isn't even on the
horizon. In comparison to alien life
forms that have the ability to travel between galaxies we are in physics
infancy. It seems obvious to me that there is a level of physics
understanding that has so far alluded us.
The interstellar Aliens may be keeping an eye on us but they
probably don’t have to. Once we figure
out physics, come up with the unified theory and start inter galactic travel,
it will be obvious that we have ‘come of age’.
And there is no reason for aliens to ‘take over the Earth’
when there are millions, if not billions of unpopulated, habitable planets out
there, for adventurous Aliens that have mastered intergalactic travel, that
don’t have the pollution problems they find here.
If we end up killing ourselves off they may wonder
down to pick through the rubble, but I doubt it. ‘There’s nothing to see here folks. Now just move along.’
