When our genes could not store all the information necessary for our survival, we slowly invented brains. But then the time came, maybe tens of thousands of years ago, that we needed to know more than could be conveniently stored in brains. So we learned to stockpile enormous amounts of information outside our bodies. We are the only species as far as we know to have developed a communal memory, and the warehouse of that memory is called the library.
Something extraordinary has been happening on the planet earth. Rich information from distant lands and peoples , has become routinely available. Computers can now store and process enormous amounts of information extremely rapidly. In our time a revolution has begun. A revolution perhaps as significant as the evolution of DNA and nervous systems and the invention of writing. Direct communication among billions of human beings is now made possible by computers and satellites. The potential for a global intelligence is emerging, linking all the brains on earth into a planetary consciousness.
The above words were spoken 29 years ago by Carl Sagan (in Cosmos 1980). Well before the personal computer revolution, the graphical user interface, before the internet had left military installations and Universities. Carl was a prophet, with great insight. He’s just described our world so poignantly, well before it arrived.
It makes me excited to be able to share my thoughts so easily, like Carl said we would all this time ago. It makes me want to ensure my digital contribution is positive and leaves a valuable legacy. It makes me want to make sure we all know how important this gift of omnipresent communication is, at a time when our species needs to collaborate so strongly for our survival.
Now that we can so quickly enter the minds of others, we should all make sure our contributions are positive, that we add something of value to this collective consciousness.
