Re: Re: Re: What is the single most important invention that shaped the last mil

Here is one of the best responses to a slightly larger time frame from Freeman Dyson - "The most important invention of the last two thousand years was hay. In the classical world of Greece and Rome and in all earlier times, there was no hay. Civilization could exist only in warm climates where horses could stay alive through the winter by grazing. Without grass in winter you could not have horses, and without horses you could not have urban civilization. Some time during the so-called dark ages, some unknown genius invented hay, forests were turned into meadows, hay was reaped and stored, and civilization moved north over the Alps. So hay gave birth to Vienna and Paris and London and Berlin, and later to Moscow and New York." He wrote this on EDGE at the turn of the millennium - now that is some thinking really!

Douglas Rushkoff – It’s not the technology’s fault

It's up to us humans to re-humanize our world. An economy that prioritizes growth and profits over humanity has led to digital platforms that "strip the topsoil" of human behavior, whole industries, and the planet, giving less and less back. And only we can save us.
