Based on first half of the story that is available online, it sounds like a jargon filled geeky utopia. Self-replicating nanobots called Nants are let loose on Mars - convert the whole planet into a sort of big AI. And they are programmed to display ads & kind of banish night from all over the world - how the hell is anyone able to see ads clearly on Martian disk from earth is beyond me. This half story indicates the big AI is learning to have it's own agenda, & will soon be out of control of humans. Second half will presumably describe its wonders.
