Why is computer science not engineering?

Something doesn't need to be engineering to be a valid technical discipline. The title inflation is nice but engineering is traditionally a licensed discipline for completely different sets of problems than putting data in a database and moving it around

At its core, Computer Science is grounded in mathematics and theoretical computation. It's more about understanding the principles of algorithms, data structures, and the workings of computer systems at a fundamental level. Conversely, Engineering applies these scientific principles to design and build practical, often physical solutions. CS professionals often engage in abstract and conceptual problem-solving, dealing with software and theoretical models. Engineers, on the other hand, are more focused on tangible, practical problem-solving, applying scientific principles to design and develop functional products and systems. In summary, while both Computer Science and Engineering are integral to technology and often intersect, they are distinct in their foundational principles, focus areas, methodologies, and educational requirements. Computer Science is fundamentally a science of computation and information processing, whereas Engineering is about applying scientific and mathematical principles to solve practical problems and build tangible solutions.

Engineering is applied calculus. CS is applied discrete math
