What types of jobs are there in artificial intelligence?

For today’s world, I can think of three:

Machine learning scientist: you basically sit in front of the computer and think long and hard about statistics and linear algebra, trying different learning models and testing them.

Robotics engineer: figuring out how to apply the latest materials and electronic components to make things move and sense the environment.

AI programmer in video games: that’s not really AI, but it’s called that because it’s about making virtual characters in a game behave as if they were smart. Most of it is smoke and mirrors, but the problems are fun and challenging nevertheless.
