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.
