There are some good points there, but I'll offer another possibility; maybe the "end" college provides is more significant than just the goal portion.
I hire people, and generally I treat a college degree as a prerequisite. Not because of specific coursework, but because the fact someone has completed a degree demonstrates an ability to keep on task for an extended period of time regardless of distractions. I don't mind major switchers, and I'm not looking for someone who did it in three years to the exclusion of life. Rather, I want to see that someone figured out how to navigate the always Byzantine requirements to get the right class into your schedule in the right order within a time limit.
Additionally, the social skills from college become pretty important - it's pretty hard to make it out of college without some kind of lab class that involves working with classmates on a group project. And everyone had someone in that project who didn't do what everyone wanted, or at least didn't pull their fair share. I want to know how you dealt with that, how did you feel about it, and what did you learn from it.
Finally, and MOST critically, I am always on the lookout for people who can write well on deadline. regardless of the technical nature of the project, the ability to explain what you are doing and why is just essential.
So yes, it's great if you can see your path in college as stepping stones to specific knowledge, but you shouldn't ignore the ancillary benefits that employers count on.
