Performance Engineer or RL Engineer

Dear all, I have an experience in performance optimization. I have worked in this field for a few years. I also have experience in C++ for many years.
Now I got an offer in RL field in a big company. It is confident.

Experience in performance opens a lot of doors. I can work in many big-techs.
But ML is growing now. And LLM probably can remove doors for C++ engineers.

Should I change my direction? I'm 30 years old now.

UPD: RL is Reinforcement Learning
