“We can’t even understand other people when we speak the same language - what hope do we have of communicating with an alien life?”
By which I mean we wouldn’t even recognise the nature of the intelligence presented to us, never mind work out how to exchange information.
It's a bit sad we can't yet fully communicate with other life here effectively. I wonder what ethical implications it would have if we ever got there. An analogy to the current state may be that of a man from another language trying to ask for directions to an autistic kid.
What does it mean to understand?
