d/acc: one year later

Vitalik Buterin argues that d/acc, or decentralized and democratic differential defensive acceleration, should guide technology so that it favors defense over offense and distributes power rather than concentrating it. He says the philosophy has matured over the past year, citing progress in open-source vaccines, Community Notes, prediction markets, ZK-SNARKs in government ID and social media, and open-source medical and brain-computer interface imaging tools. The first d/acc event, "d/acc Discovery Day" at Devcon, featured a full day of speakers across bio, physical, cyber, info defense and neurotech. He presents the approach as an alternative to e/acc-style acceleration without defense, centralized control, and deceleration.
