"The analogy is clear. PROMs are Programmable Read-Only Memory chips," Hiro says. "When they come from the factory, they have no content. Once and only once, you can place information into those chips and then freeze it—the information, the software, becomes frozen into the chip—it transmutes into hardware. After you have blown the code into the PROMs, you can read it out, but you can't write to them anymore. So Lagos was trying to say that the newborn human brain has no structure—as the relativists would have it—and that as the child learns a language, the developing brain structures itself accordingly, the language gets ‘blown into' the hardware and becomes a permanent part of the brain's deep structure—as the universalists would have it."
