“...we know no more about what these are than we knew 50 years ago...”
Since you can so easily probe the secrets of the inner sanctum of government intelligence, can you give us some more gems.
“can you give us some more gems.”
I think it speaks for itself. Do we have tech today that is leap beyond, something we have adapted from ‘them’? I don’t believe we do. Since WWII we have advanced our tech, but at no point have we had a tech/material/discovery that is a large step ahead. Since the discovery of the transistor, we have advanced incrementally.
My point is that IF we had gained ‘alien tech’ in the last 50 years, we would see it. And we don’t. So, either these things are so much beyond us that we’re unable to interact or communicate, or we’re really unlucky at being able to catch one, in fifty years of trying.
