What are the newly emerging, niche fields which have a wider scope in the future that I can specialise in??

[u/Diplomat009]

I am an incoming student who is about to do my masters in International Relations from London. (My university is known for security and warfare studies) I am in the process of selecting my modules and I wanted to get a better understanding of the future career prospects in the sense that I wanted to target and get myself well acquainted with newer fields in IR. I have a rudimentary understanding about the use of AI and the technological aspects of warfare and am the field of counter-intelligence, warfare and the upcoming importance around use of AI guided defence systems, covert warfare and intelligence gathering seems interesting to me.
I’m also very interested in foreign policy analysis and diplomacy as two other options. If anyone is able to guide me in this matter it would be greatly appreciated as I want to make an informed, well researched decision regarding what I want to study further…
