Alvin Toffler on the Modern World/Age

Alvin Toffler on the modern world/age in "The Third Wave" (1980):

Until now the human race has undergone two great waves of change, each one largely obliterating earlier cultures or civilisations and replacing them with ways of life inconceivable to those who came before. The First Wave of change – the agricultural revolution – took thousands of years to play itself out. The Second Wave – the rise of industrial civilisation – took a mere three hundred years.
(First chapter)

Some historians may take issue with the way this book divides civilisation into only three parts: a First Wave agricultural phase, a Second Wave industrial phase, and a Third Wave phase now beginning.
(Introduction)

A new civilisation is emerging in our lives, and blind men everywhere are trying to suppress it.
