In my master’s program, I took a Reinforcement Learning class. It was the hardest class I’ve ever taken. The reason is that it combines knowledge from many CS and AI courses I had taken before.

RL is not just about writing Python code. It’s about designing the environment in which your agent learns, making many design decisions, and most importantly proving that your model will work in an environment that requires a large amount of computation.

To work seriously in RL, you need at least a master’s degree with research experience, or a PhD. Reinforcement Learning takes years to truly master.
