At the dawn of life on this planet, evolutionary changes happened slow. Billions of years slow. One microbe took billions of years to evolve the DNA necessary to replicate itself from simple amino acids. But that first copying mechanism, DNA, allowed information to be transmitted that much faster. Then, evolution only took millions of years to create multi-cellular creatures. Good information was kept, and bad information was discarded. The wheel of time continued until evolution presented the planet Earth with a new species — human beings. Except this species was different — this was the first intelligence on the planet.
This is where the evolutionary process of life really began to accelerate. Instead of millions of years to the next paradigm shift, it was only 50,000 years until Man began to talk. And then, only 10,000 to develop agriculture, written language, society, and government. Another 5,000 elapsed, and we had constructed Pyramids, developed theological and monetary systems, and had begun colonizing the planet. This led to the development of Science a few thousand years later. Science, after a few mere centuries, gave rise to the Industrial Revolution, which after only 50 years gave us the Computer Revolution. Notice the trend? Evolution is a feedback loop.
“Moore’s law describes a long-term trend in the history of computing hardware, in which the number of transistors that can be placed inexpensively on an integrated circuit has doubled approximately every two years.”
When Moore made this prediction at CalTech in the 1970’s, computers were the size of buildings. Now one fits in your pocket, and a particle accelerator in CERN is capable of achieving the coldest temperature in the universe and a magnetic field thousands of times more powerful than the Earth’s– all to find the God Particle that allowed the universe to be created. Forty years ago a machine that sized could barely run Pong.
This is only the beginning, however — imagine the things we will achieve with computers the size of red-blood cells floating inside the body. Nanobots will soon be integrating themselves into our biological structure, repairing broken synapses in the brain, cleaning out arteries and creating a virtual-reality interface within your visual cortex. Don’t believe me? Ask Ray Kurzweil, who this year co-founded the Singularity University in Palo Alto with Google and NASA. Their sole mission is to create a human-computer hybrid that will allow us to live forever.
Why a hybrid? Why not simply create a smarter-than-human computer and have it solve all our problems? Because that computer might decide that keeping us humans on Planet Earth would hinder its own progress in evolution — that we pose a threat to its survival. Or, the computer might even convert the entire solar system into a bigger version of itself to solve the problem. In Isaac Asimov’s “The Last Question”, scientists keep building bigger and bigger computers; while constantly asking the meaning of life. It is not until the very end, when, after the entire universe has been converted into a computer that the final answer is given.
The UN even recently passed a law banning “self-replicating nanobots” to prevent the planet from being covered in a “gray goo” of robotic microbes. This only supports how real this is all becoming. Six years ago, Facebook was being invented. Now, 500 million people have moved parts of their lives “online”, and could not imagine life without it. Ten years ago, cell phones and laptops were only just becoming commonplace within the societal lexicon. Now, having a desktop or even laptop computer is viewed as being a nuisance and hassle. In the next ten years, however, the change will be faster. We know this because it’s been speeding up this entire time.
Every day, more things happen than the day before– because today we have better tools for communicating, working, living, and replicating information than we did yesterday. The move from analog to digital will be almost too gradual to notice, but one thing is certain: Humanity is uploading itself onto the internet, which now appears to have turned Planet Earth into a collective brain; every human being a neuron in the system. This collective brain will soon abandon the mortal problems we face today, but it will face problems on a universal scale. Like how to prevent its collapsing, parent star from dying, how to exist in multiple dimensions, or even how to better allocate intelligence throughout the universe.
Maybe then it will even send out tiny seeds to land on distant planets…just like the amino acids that landed on Earth.
