I think it’s a continuum. Sure, I freely admit that I’m still rather ignorant when it comes to the low-level details of my computer. But compared to the understanding I get from Windows or Ubuntu? From that point of view, I’ve learnt a lot.

Besides, it’s not like this knowledge is useless. I now find myself being able to diagnose and fix problems with my system which previously I was clueless about. And it makes it a lot easier for me to learn the lower-level details if I so choose.
