I don't understand his reasoning.

Once a civilization is thriving in space, materials are practically infinite, and self building factories mean that the only budget is time.

Personally I think that the great filter is surviving the pollution and climate destruction from a civilization's industrial revolution. And that very few civs make it past that to thrive in space. So we may get a big space faring civ every 10 million years or so, and we don't know whether a civ would stay as a space farer forever.

Unless there really is a whole field of physics that we haven't touched yet. If that's the case, all bets are off.
