The current times and future all belong to AI, and it is here to rule for a long time.

“Project management skills” is a broad term that includes:
- Leadership

These skills are useful in many jobs and become even more important if you move into a manager role.
You can also choose to build a full career as a project manager if you enjoy organizing people and tasks to reach big goals.
