I would suggest you to opt for Artificial Intelligence (AI). Keeping in mind where we ourselves in the next few years, AI has literally blown through the scenes and the results are mesmerising. There's no doubt about the fact that the world would be needing more AI developers in the coming days and thus I consider learning as a secure career option as well! But end of the day it entirely depends on what your interests are and what you are fascinated with, so decide accordingly!
Good Luck!
