"Along the way, all meaning was lost except for verbal signals, the kind of signals any animal species develops in order to stay in touch with its own kind, call others to a feeding spot, or alert others to danger. Every linguist should know that language must be used to be retained, and the compilers of this report have warned that human language on Earth is also being reduced. As humans become more crowded, they become less tolerant of variety. To fit into a crowd, people must be similar, and Earth’s population today is a vat of homogeneity with only a pretense of choice remaining. One may pick model x with one curlicue or model y with three, the tasteless brown cracker or the tasteless yellow cracker, the actual difference in either case being nil. Any real choice among things of unlike value might lead to disparity, which leads to conflict. Ideas also contribute to disparity, and therefore in crowded populations ideas must be restricted to the least controversial, the least interesting. Children all receive the same grades in school. Workers all receive the same pay. Clothing is similar; Foods are identical; and with the passage of all distinctions the words for them also pass."
