I think you'll want to first choose your principles and set some priorities, and only then choose your best path. At age 61, I'm nearing the end of my professional journey. Initially, I chose jobs that solved "sweet" technical problems, often AI-related or computationally hard, on behalf of the military or intelligence agencies. In time, I began to question the value of those missions and left to seek a legacy involving less "collateral damage". After a stint in academia (which I eventually felt was too tangential to real world concerns to make a real difference), I moved into healthcare. After 13 years, I'm still involved in AI (image analysis), but here it's on behalf of making drugs that treat diseases that are largely incurable: cancer, alzheimer's and ALS, HIV vaccines, etc. Yes, the short term economic priorities of large corporations are sometimes troubling. But my role isn't to maximize profits; it's to enable scientific breakthroughs that can make lives better and longer. And I can live with that. Likewise, I think you'll need to decide these things for yourself.
