Crystallizing Data and Information

Human Body Version 2.0 by Ray Kurzweil:
"A radical upgrading of our body's physical and mental systems ... By 2030, reverse-engineering of the human brain will have been completed and nonbiological intelligence will merge with our biological brains.
"Once nonbiological intelligence gets a foothold in our brains (a threshold we've already passed), it will grow exponentially, as is the accelerating nature of information-based technologies. ... By 2040, the nonbiological portion of our intelligence will be far more powerful than the biological portion. It will, however, still be part of the human-machine civilization, having been derived from human intelligence, i.e., created by humans (or machines created by humans)...
The explosive nature of exponential growth means it may only take a quarter of a millennium to go from sending messages on horseback to saturating the matter and energy in our solar system with sublimely (super)intelligent processes.
