From his site:
“Reinhold Popp is one of the few university lecturers in German-speaking countries who are systematically involved in future-oriented research. Based on scientific analyses, he creates realistic images of the future, beyond destructive doomsday moods and uncritical everything-will-be-okay optimism. Several publications by Professor Popp are regarded as standard works in German-language futurology and futurology. Far beyond the world of science, Professor Popp is known to a broad public through his around 1400 reports, interviews, columns and comments in the press, radio and television as well as his lively lectures.”
