Cornucopianism is the idea that continued supply of the material needs of humankind can be achieved through continued advances in technology. It contends that there is enough matter and energy available for practically unlimited growth.
The term comes from the cornucopia, the "horn of plenty" of Greek mythology, which magically supplied its owners with endless food and drink. Adherents are called "cornucopians" or sometimes "boomsters," in contrast to doomers, whose views are more aligned with Malthusianism."[1]
