An SE is part of the "business". Often an organization has many projects that need to be done, so time estimates are critical to determine when the next project can start. It's an important skill to have. You're not "playing" with tools. You're learning to use them to build stuff of value to someone. And that's the point: SE majors should work on real world projects using modern tools. My contention is that SE should be a separate academic department from CS in the same way the EE is separate from Math and Physics. CS professors would continue to teach CS and very definitely not SE.
