Anders Sandberg’s talk asks a classic long-horizon question: how fast could humanity actually build a Dyson sphere?
The poster frames it as a quantitative engineering problem, not pure sci-fi hype. The discussion is about the scale of the project, the constraints that dominate it, and what “fast” could realistically mean for a civilization-level buildout.
