 We are the Dreams of a Future AI

An evolving cyberspace becomes effectively ever more capacious and long lasting, and so can support ever more minds of ever greater power. If these minds spend only an infinitesimal fraction of their energy contemplating the human past, their sheer power should ensure that eventually our entire history is replayed many times in many places, and in many variations. The very moment we are now experiencing may actually be (almost certainly is) such a distributed mental event, and most likely is ...

 Computronium

In programmable matter, the same cubic meter of machinery can become a wind tunnel at one moment, a polymer soup at the next; it can model a sea of fermions [elementary particles], a genetic pool, or an epidemiology experiment at the flick of a console key. Ten times as large a simulation will simply require ten cubic meters of machinery, instead of one. Flexibility, instant reconfigurability, variable resolution, total accessibility, and handling safety make such programmable matter worth a ...

 Human Communication with Matrioshka Brains

Communication between humans and MB is essentially pointless.  The computational capacity difference between a MB and a human is on the order of 1016 (ten million billion) times greater than the difference between a human and a nematode (~109)!  A single MB can emulate the entire history of human thought in a few microseconds.  It is important to consider that intelligence may not be a linear process.  There is a rather large difference between the...

 Matrioshka Brains

Matrioshka Brains (MB)1 are megascale computers constructed out of microelectronic and/or nanoscale components.  MB may be constructed as shells around a star (internally powered Matrioshka Brains: IPMB) or may be constructed independently of a star if large amounts of power are harvested from stars in other locations and beamed to the MB (externally powered Matrioshka Brains: EPMB).  A third variant, (self-powered Matrioshka Brains: SPMB) which generates power via controlled n...
