There is a hubris here in thinking that everything that humans imagine can eventually be technologically created...the hubris is in the idea of going beyond Nature, and the nature of things ("atoms/void").
Regarding the word hubris:
QuoteEnglish picked up both the concept of hubris and the term for that particular brand of cockiness from the ancient Greeks, who considered hubris a dangerous character flaw capable of provoking the wrath of the gods. In classical Greek tragedy, hubris was often a fatal shortcoming that brought about the fall of the tragic hero. Typically, overconfidence led the hero to attempt to overstep the boundaries of human limitations and assume a godlike status; in response, the gods inevitably humbled the offender with a sharp reminder of human mortality. Take, for example, the story of Phaethon, a mortal son of the sun god Helios. In his hubris, Phaethon drives his father's sun chariot into the heavens but loses control of its horses. The chariot begins to scorch the earth, and Zeus strikes Phaethon down with a thunderbolt.
