That's a fun visual and I never knew about it, but can't help but immediately think about the 'Hey Mom! How are you doing? You look obese. Your arteries are completely clogged.' analogy of self-destruction in humans, even though it's not a great comparison. But I think aliens or a higher power or some more evolved species would look at many things humans do - or don't do - and think we're brain dead.

I think it's about the idea that blindspots are obvious to everyone but the being with that particular blindspot.
