💬 Eric Hughes: "Code Is Not Enough" On March 14, 1996, the author of the "Cypherpunk Manifesto" and the famous phrase "cypherpunks write code," Eric Hughes, comes to the conviction and shares his own opinion that code alone is not enough: "Perhaps the single most important lesson I've learned from cypherpunks is that code alone doesn't cut it.
