These are the facts.
It has all the advantages of biology and machines. It grows, reproduces, and evolves like something alive. It has suffused itself into the biosphere, and not living thing remains uninfected. It is specialized and powerful like something mechanical. It has suffused itself into all human technology, and no machine is uninfected.
The closer you get to the equator, the more solar energy is available to feed its intensive processes. Here everything is part of one system, constantly adapting, improving, and integrating. It incorporates everything into itself, growing its own interfaces. There is less distinction between machines, animals, and humans every day.
The farther you get from the equator, the less solar energy is available and the slower it grows. Up here, there are still humans. They are infected just like everything else, but able to pick up a wrench without gaining a wrench-hand. Nothing is uninfected, but those last humans have the luxury of choosing how human to be.
Notes: How about an RPG where your inventory levels up instead of your character.
