Honestly, I don't believe it. I know nothing about music, but at least in my field of study (computer science) I doubt this can apply.
There is a limit and it is very plain: time. You can only soak in so much knowledge at a time, and knowing in theory is very different from knowing in practice (but you definitely need both). Practice takes time, especially if you practice to understand theory. You have to make mistakes, they are the single most important thing to understand something in my experience. You need the "haha" moment when you understand why something doesn't work and how it has driven theory/research in the field.
You can go maybe go faster than the computer science program at X. Maybe twice or thrice as fast, if you're gifted. But you cannot go as fast as you want, that is just wishful thinking.
