Four hundred years ago, almost no one on Earth had tasted coffee. It was too difficult to move things a few thousand miles.

A hundred years ago, if you wanted a cold drink in the summer or needed to ice an injured knee, you were largely out of luck. It took millions of years of cultural and technical evolution to get to the point where people had a freezer in their house.

The industrial revolution was mighty indeed. It paved the Earth, created the middle class and changed everything. And it was a powerhouse for generations, incrementally changing what hadn't been changed yet.

The TV revolution followed, introducing mass marketing as a force that could change our culture.

Then, the 60s brought the computer revolution, which involved large devices capable of sorting, calculating and processing things that were previously unsorted.

We're living right now in the connection revolution, one powered by the internet, in which people connect to people, computers connect to computers and our culture changes ever faster, daily.

The next two revolutions are right around the corner:

The biology revolution, which has had some fits and starts, will transform our bodies and our planet. Once computers are able to see, understand and modify living things, the same acceleration of the last three revolutions will kick in.

And the AI revolution, in which we engage with computers as much as with each other, is showing itself now too.

Faster, ever faster. Moore's law ratchets technology, technology changes the culture, the culture changes the economy and it continues.

Revolutions are impossible, until they're not, and then they seem totally normal.

Iced coffee, anyone?
