3.1.1. Different ideologies have always shaped how humans see and steer the world.

3.1.3. So far, in the 21st century, technology seems to have all competitors beat. It’s the thing we most believe in.

3.1.4. With technology being our prime ideology, data becomes the most valuable asset. That’s why politicians struggle for their nations to win the giant tech race.

3.1.5. The problem is that this time around, no one fully understands the implications of our ideology.

3.1.5.1. Just look at the financial markets, where algorithms already do most of the work, with very few traders grasping what’s actually happening.

3.3.1. Sadly, our schools only teach us the latter.

3.3.3. A basic understanding of history, biology, math, and other subjects is important, no doubt.

3.3.4. But beyond that, it’s more important that we learn how to navigate the modern sea of information, how to filter out the important, and how to determine what’s downright false, than just remembering more facts.

3.3.5. With more data being created now in a single year than the past few millennia combined, future workers won’t need to know as much as possible, but how to find out only that, which they really need to know.
