I don't agree. Most people simply don't work very hard. For a motivated person, 1 year on their own time can easily be enough time to replicate a bachelor's in CS. When I did my bachelor's I was a young dumb kid who partied a lot and wasted a lot of time.

Now, 14 years later and tons of industry experience, I realize how trivial the material in my CS bachelors was and really the big problem is that most students don't really work that hard. Now my work ethic is much, much better, and I've been learning far more advanced material, far faster than I ever did before, because I come home in the evenings and actually study (using online options) and practice.

When I look back at college level CS, it's a joke. Also, the online resources are built to actually be taught well, when I was in school, there was no Khan Academy, Pluralsight, Coursera, Udemy, etc. Most college professors are research oriented at heart and are uniformly terrible teachers. The online moocs and so on are focused on actually making things easy to learn, which gives modern learners a massive advantage.
