Artificial intelligence and moral issues. Towards transhumanism?

As artificial intelligence travels through the solar system and gets to explore the heliosphere (enclosing the planets), it will adapt by making decisions that enable it to do its job. Many people in the field of astrobiology are in favour of the so-called post-biological cosmos vision. Is it because of the desire to conquer space that we humans are sowing the seeds of our own destruction in favour of artificial intelligence? Or are we unconsciously following some sort of master plan in which flesh and blood beings are destined to become extinct and be hybridised by silicon and synthetic materials? As for the mind, memory, consciousness, could there also be a place for humans in a robot's brain?
