Value is dependent on perception, perceived value. If the average human is unable to perceive the value of, let’s say, intelligence, intelligence would then have no value. Worth is measured by popularity amongst the masses, not by any measurable benefit to mankind. If you want to understand the bigger issues, it would be telling to examine the popularity of Beanie Babies or any number of other purposeless, meaningless trash we hold dear. We gave civilization, civilized society a solid shot. We’re just not capable of it. As we attempt to search the cosmos for intelligent life, it’s reasonable to believe that we’d be better served to start here, on Earth.
There is simply no need to waste resources building a spaceship to conduct a futile search for intelligent life when you could simply drive around in your car and achieve the same result.
