Science Quote by K. Eric Drexler

The sentence tilts the camera away from today’s lab bench and toward tomorrow’s endgame, and that’s the point. Drexler isn’t selling nanotechnology as a neat suite of incremental tools; he’s trying to discipline the conversation around a discontinuity: the “assembler breakthrough,” his shorthand for programmable, general-purpose molecular manufacturing. By naming that horizon, he implicitly argues that the technology’s meaning isn’t captured by current nanoparticle coatings, medical delivery systems, or materials science wins. It’s captured by what happens if you can reliably build complex products atom by atom.

The intent is strategic: set the terms of debate before the debate gets domesticated by near-term applications and benign PR. “Most important” is a power move, elevating foresight over hype management. The subtext is a warning about category error: if policymakers, investors, and the public treat nanotech as just smaller engineering, they’ll miss that assemblers would reorganize supply chains, security assumptions, and even geopolitical leverage. The question “what it will look like after” smuggles in inevitability, too; it frames the breakthrough as a destination rather than a speculative branch, nudging readers to plan as though it’s coming.

Context matters. Drexler’s career has been a long argument that molecular manufacturing is both plausible and transformative, and that the responsible stance is to model second-order effects early: abundance alongside weaponization, decentralization alongside control. The line works because it’s calm, almost managerial, while pointing at an upheaval. It asks you to stop gawking at the prototype and start grappling with the civilization-level product roadmap.
