What field (Ai, ML, VR, AR, CLOUD, HARDWARE) will be the most lucrative/hot for Product Management in the next 5 years?

I'm gaining good pm experience at my current company. I would like to understand what space is going to be the most sought after for good PMs in the next 5 years? Why? What should be the goal of an APM to grow quickly? 100k, 2 YOE Update: added poll
