Further Thinking
“Space, the final frontier. These are the voyages of starship Enterprise(进取号星舰), its continuing mission:
to explore strange new worlds,
to seek out new life forms and civilsations,
to boldly（勇敢地） go where no man has gone before.”
——James Kirk (Star Trek星际迷航）
frontier: a border between two countries;
a wilderness at the edge of a settled area or a country;
an undeveloped field of study
final: implying there were other human frontiers before space, such as physical
frontiers( the discovery of America, the Arctic and the deep sea); and scientific
frontiers( advances in medicine and technology)…
Space: the final frontier: Space is the last field that remains mysterious and unknown to
mankind.
While I support space exploration, I don’t think space is the final frontier just yet. There is still much to learn about the earth, and we are only at the very beginning of new technological breakthroughs involving information technology and AI. There are many scientific and technological frontiers all around us.
