The Core Difference
Software engineers build systems; data scientists extract insights from data. An engineer asks "how do I make this work reliably at scale?" while a data scientist asks "what does this data tell us?" Both use programming, but engineers focus on software architecture and system design, while data scientists focus on statistics, machine learning, and analytical storytelling.
