Many of those questions aren't particularly useful either. They may be interesting from a philosophical perspective but that's the language of thinking, not the language of doing. I've written code in assembly language. I've looked at the output in binary. I can explain in basic terms what is happening there. Does that help anybody?
I would argue that it doesn't because almost everyone writes code in higher level languages. Even if I can tell you what I know it doesn't provide any practical information for you to use. Similarly, I could explain to you how long division works but the next time you need to divide two numbers you're still going to reach for a calculator instead of a pencil and paper. What then is the point of lamenting the loss of knowledge that no one uses directly? It could be reconstructed from what remains if necessary but since it isn't necessary it doesn't matter.
The fact that people don't like Skyler is intentional. At some point you're supposed to ask "why am I cheering for the drug dealer over this woman"? That disconnect is a huge part of why the story is so engaging. They make you root for the bad guy over the good guys, even when you shouldn't.
