In 2026, what field should a computer engineering student focus on, and what roadmap should they take?

As a third-year computer engineering student in 2026, considering the impact of AI on coding and engineering practice, what will companies expect from me? Which field should I choose (AI, data engineering, cloud DevOps, cybersecurity, full-stack web, or mobile)? In this period of transformation, what kind of roadmap would you recommend I follow? I’m requesting a comprehensive, forward-looking mentorship perspective.
