Now a nonagenarian, science fiction legend Arthur C. Clarke is still waiting for evidence of extraterrestrial life--the first of his three 90th birthday wishes is for "some kind of signal" from some kind of life form, emanating from somewhere out there. He's also optimistic that humans will soon be traveling by the thousands into orbit and to more remote destinations in the next half-century.His other two wishes have to do with economic and political challenges right here on Earth.
