Elon Musk predicted the disappearance of entire countries and cultures due to a decrease in global birth rates. The American entrepreneur referred to a publication that claimed that the total fertility rate in Italy and Japan is 1.0 and 1.4 children per woman, respectively. According to the publications author, if this trend continues, each successive generation will be about half the size of the previous one. "This means that entire countries and civilizations will disappear forever," Musk wrote.
