It's all about what you want to do. It's a bad idea to go to college without a plan.
But let's put the question another way. What jobs that have traditionally required a college education (i.e. specific degrees) are going away? It seems to me like the core things are still going to be around for a while. Medicine, law, engineering, teaching, a multitude of sciences, and a variety of others.
Yes, there is a LOT of fluff in college. Tons of absolutely useless degrees. There have been for a long time. But if you are spending $100K plus for a degree in underwater basket weaving with the expectation of landing a great job when you graduate then you clearly haven't thought things through.
Also, learning things on your own is nothing new. The Internet has made it somewhat more convenient but there have always been books and if you happen to live near a college you can attend lectures for free. Getting a degree is like getting a certification. It's a way to prove to a prospective employer that you have some base amount of knowledge in the areas that you need. Obviously that requires that you are actually getting education in areas that are needed.
