Senior Engineer Dilemma: Pure AI vs. AI + Data for Long-Term Career

A senior data engineer with 18 years of experience initiated a Reddit discussion, torn between focusing on a "pure AI architect" path or maintaining a combined "AI + Data Engineering" profile for the next decade.

Conversely, staying broad raises fears of lacking the deep specialization that the market rewards at senior levels.

The author asks the community which path is more secure long-term (10-15 years), which pays better at the leadership tier, and whether a "data foundation" provides a real moat or has merely become table stakes.
