I do security R&D. I chose security in uni because it sounded sexy. Honestly, you sound like a pessimist. I don't work with networking often and only read papers I'm interested in. Same for neural nets, I could rattle off 3 idea that no one is working on. I don't think the field is saturated. Just look at what you enjoy doing and specialize in that. You don't need to mixmax the decision and try to predict the future.
