Yesterday, Ethereum creator Vitalik Buterin published a long blog post outlining a new philosophy of techno-optimism called d/acc. As part of this philosophy, Buterin advocates a balanced approach to technological development, focusing on technologies that provide protection, decentralization and prosperity for humanity. This represents a counter-argument to the rampant techno-optimism put forward by figures like Marc Andreessen. Buterin calls for more collaboration and "purposeful management" of technology.
