No human could ever do this, for in these purely computational matters, machines are vastly superior to us, and always will be.
In some twentieth-century science fiction visions of the future, humans created friendly robot sidekicks with data storage capacity and computational speed the human brain lacked.
Think of how a few thousand years of human civilization got us to a certain amount of computational power.
The availability and propagation of cheap sensors, cheap storage, and cheap computational cycles will allow humanity to develop a collective memory of the activities and outcomes of everyone on the planet.
Distributed computing makes enormous computational problems affordable to solve.
