Just interesting. "We are only seeking Man". Not Woman. Because even genius Lem thought that man and woman can be described as one word "Man".
Actually our civilisation will be prepared for contact with another worlds, not earlier than after accepting the fact, that man and woman are aliens to each other. They cannot understand each other, they don't have to understand each other, and they should to be happy about it
