If you want a job now, as in right now, software development is the best place to start. If you want a job soon that leads to other branches like AI, machine learning, cybersecurity, hell maybe even data science, software development is still the way to go.

If you know of an opportunity you will be able to get a data science job at Facebook or Google, then I would go with that. I guess my point is that it depends what your situation is, but software development has the most potential now.
