Need Career Advice As a Prospective University Student

Hi, next year I will start to study in a top european business school(non-uk) as a non-eu national. However I am not really sure about my career choices. I am mostly interested in macroeconomics, geopolitics and computer science (I know last one isnt really related to others but I know a few languages mid level so why not mention it). Which kind of field would suit me best? Also which kind of field would be less affected by AI compared to others? IB kinda seems like a safer option but I am not sure if I will enjoy it considering my interests. I know AI can not fully replace humans right now but it certainly decreases the need of labor which will naturally increase competition. And lastly what would your suggestions for the summer be? I am not really a competitive person but rise of AI made me really anxious about employment. Thanks for your help in advance :)
