Defining

I am a Software Engineer with over 4 years of experience. I am currently at a point where I need to define the correct, long-term career pattern that I can commit to and follow as the industry evolves with AI Era. In your experience, what specific specialization offers the most stability and growth for the next decade of an engineer's career? My thinking was becoming a Cloud Native Engineer and find a Master program to upgrade myself. Do you guys think that is the best approach ?
