We can end robots to mars, Put a man on the moon(???????) We can explore the deep trenches in our oceans, we build colossal buildings, achieve some astounding scientific breakthroughs, We have the power to blow up the planet, but as yet we can not know what or change what others think.
Even guessing what other think at any given time, you have a grreater chance of winning milions in the lotto three consecrative times in a row than guessing what they really think.
It is a futile endeavor in which you ae the only player.
