I was always curious and hungry for knowledge as a kid, but what I lacked was the knowledge of where I can find more knowledge (the libraries in my childhood were crap; the most complex computer book was how to use Office). It wasn't until university that I realized how to research things and find the best resources to learn that I truly was able to teach myself. That happened at the end of my 3rd year of university, and my 4th year was spent barely attending class and instead teaching myself the required material on my own time, while I was also learning about things not taught in class.

I don't know very many people who can do this. Most people I know, once they're out of school, learning stops. It's not that they can't learn anymore, it's that the impetus to do so ceases once they're outside an environment designed to facilitate it. I, and I suspect most autodidacts, have to leave said environment before I can really get engaged.
To answer this correctly we'd have to get philosophical, which means we'd both end up correct.
Suffice to say that I believe everyone is capable of learning to become a learner. You'd be surprised at what little knowledge we're born with and what our society has created for us (so-called "constructs" in philosophy parlance). Don't discount the ability for the human mind to be taught.
It's probably not a coincidence that those willing to go against the grain with respect to education seem to be disproportionately represented among the successful entrepreneurial class.
This entire discussion reminds me of the "mappers" vs "packers" theory. It's a bit long winded but a good read:

It's possible that is the case. I don't think it's by any means proven. But all of the autodidacts I've ever read about, and known, myself included, managed to be able to completely ignore the effects of compulsory education and forge ahead despite active discouragement from society.
Simply removing the compulsory aspects of education is, as far as I can tell, not going to be able to create this sort of resiliency, even if it improves the ability to learn. Perhaps they won't need it, I don't know.
AFAICT, many people learning the kinds of things I prefer to learn about when they are out of school, but they seem to continue to learn things (even if they are things that I don't value, or even things I consider to have negative value, both to the learner and to the society they are in.)
I have found that all the successful people I know had a similar approach to learning. Instead of being complacent with education, they made it work for them, whatever approach that may be. A crappy professor would be fixed by either going to a different lecturer, seeing the professor after hours, discussing the subjects with upper years, going to the library, and so on. Basically, they took control of their education and made it work. Reading the biographies of all the people mentioned in the article, I get the feeling they were like that as well. The fact they dropped out is almost completely irrelevant to their success.
