Is Pega worth learning, or should I be getting ready to jump ship?

I'm a full-stack developer working for a large company. Specifically working with Angular and Java.

Word on the street is that the application that I'm working on will eventually (within the next 18 months) be rolled into Pega, and the team I'm on will be trained to continue developing within the Pega application.

Any Pega developers on here? What are your prospects like? I'm not exactly thrilled to make the switch, as I still see a full-stack skill set as more marketable than being boxed in by Pega. But again, I literally have no experience with Pega or what that would look like.
