Stanley Kubrick on the Universe

"I'd be very surprised if the universe wasn't full of an intelligence of an order that to us would seem God-like. . . .There are approximately 100 billion stars in our galaxy alone and approximately 100 billion galaxies in just the visible universe . . . where intelligent life . . . is hundreds of thousands or millions of years in advance of us. When you think of the giant technological strides that man has made in a few millenia - less than a microsecond in the chronology of the universe - can you imagine the evolutionary development that much older life forms have taken? They may have progressed from biological species, which are fragile shells for the mind at best, into immortal machine entities - and then, over innumerable eons, they could emerge from the chrysalis of matter transformed into pure energy and spirit. Their potentialities would be limitless and their intelligence ungraspable by humans."

But why don't they just say "Hi"?
