I didn't take the GP seriously because of this. Papyrus and clay and stone carvings do not equal operating a network of brittle, bespoke devices across the scale of a solar system. The existence of language, or writing, or even cathedrals or pyramids, do not eclipse this accomplishment. The odds of losing control of a system is proportional to both time and complexity of the system, and the GP ignores the latter factor.
