Smart review: introduction

There are 7.674 billion people on this planet. Of those, how many are working on innovations that will make the world a better place? A few thousand people? Maybe a hundred thousand, a million?

And what about the other 7.673 billion people? Sprinkled throughout are some truly brilliant individuals, people who are capable of amazing innovation, but for one reason or another, aren’t in that line of work. Even if we consider only the sharpest 0.1%, that’s still millions of people.
