Planning to apply for masters, please suggest domain of study

Objective is to study something interesting that can also help with employment somewhat. Earning more money is not my primary objective.

MBA doesn't seem relevant enough, I'm already bootstrapping a venture and learning on the go. Would prefer just starting up than studying about it in college. Course material mostly seems boring and irrelevant.

Experienced in design, UI UX, content, marketing. Bachelor's was in design.

Not sure which one is most relevant with the rapidly advancing improvements in AI. Almost feel like studying philosophy at this point to try and make sense of current and future world.

Suggestions are welcome.
