Today my mother turns 55 years old. I’m sure she wont mind me sharing that detail with you. The year she was born, 1956, IBM invented the ‘Hard-Drive’ – it weighed 1 ton & held 5 megabytes. A little more than a half-century later, & my mother owns a telephone that holds three thousand times more than this. In fact there is greater processing power in her pocket than there was on the whole planet the year of her birth. I shudder to think of what terrible parallel anticipates my own 55th birthday.
