The passage of time and growth of our world - its people,

the environment and our technology - is a remarkable

occurrence. For parents, watching a baby grow into an

adult happens in the blink of an eye. Builders erect skyscrapers

and condominiums faster than you think is possible.

Companies like Tesla, with their electric cars and

lithium-ion batteries, are changing the way our society

perceives automobiles and energy. And the rate at which

these fundamental shifts become realities increases with

each passing year.

Don’t worry, the book you are reading is about digital

marketing, but I mention the way the world is changing

because digital marketing and the Internet are at the core of

these monumental innovations.
