The Great Voyage Organization really had left. After all, they had only been passing through, and had merely happened to encounter a "Golden Record" in the two-dimensional world, which in turn led them to find the Gourd People.
Besides, the various civilizations of The Great Voyage Organization had taken what they needed here. Although they still had not directly mastered Quantum Macro Tunneling Technology, each of them had acquired a two-dimensional biosphere, giving them a steady stream of materials for research. There was no need to remain here any longer, because the road ahead was still very long.
Just as Aike had written in his memoir, after the gods crossed this two-dimensional world, they would head toward the unknown depths of the universe.
Of course, after leaving, The Great Voyage Organization did not stop researching quantum macro tunneling. They studied as they traveled, while also exploring whether any other two-dimensional civilizations existed near their route.
Unfortunately, until The Great Voyage Organization left the two-dimensional world, they never discovered a second two-dimensional life-form.
From this perspective, the two-dimensional Gourd People were fortunate. They had encountered The Great Voyage Organization. Otherwise, throughout their growth, they might always have believed that they were the only civilization in the entire universe, and that the entire universe was this two-dimensional world.
If things had developed according to that logic, the two-dimensional Gourd People would have believed themselves to be alone, and might therefore have gone down another path.
Perhaps in the near future, they would have gained the ability to step out of their own Star System, then explored the "entire universe," caught up with the "Golden Record" they had launched long ago, and continued exploring the universe. In the end, they would have discovered that aside from themselves, there were no other civilizations in
