The article Grand Challenges: Building a synthetic sensory-motor system said
The real grand challenge for life on Earth is, as it has always been, to conquer new ecological niches. And this challenge has been taken up successfully from the seas to the surface of the earth, to the skies. But nature’s evolutionary techniques imply a gradual colonisation of new ecologies: and there are limits to the ecological niches that traditionally evolving living entities can colonise. Life has reached these limits: there may be other colonisable places in the Universe, but the vast emptiness of space between here and there presents an unbridgable gap for traditional evolution.
Yet there is energy available from sunlight within some parts of space to support life, though the distances between the energy sources is very large. We can build electronic systems which can survive these low energy periods, and perhaps transport them to other stellar systems. But what is gained by simply transporting automata? Is this “the conquering of space”?
One possible solution is building truly enormous spaceships with complete ecologies, to travel space. Unfortunately, the time problem remains intractable: the science-fiction scenario of generations upon generations living on such ships does not seem attractive unless one is fleeing from some cataclysmic event on Earth. Rather than waiting for such events, let us consider an alternative…
