1. Creativity - you can create anything from typing words and a little electricity - office programs, new medicines, predicting cancer from images, robots, planes, satellites, rockets that put people to the Moon or robots to Mars - all use machines programmed with code.

2. Challenge - some of the projects and algorithms are so complicated that full understanding of them is great challenge.

3. Freedom - you only need a laptop and internet and a bit of electricity and you can code from anywhere on Earth or if you’re Astronaut you can even code from space.
