I feel similarly. On the other hand a good intuition about memory representation is important: the difference between global and automatic variables, linker visibility etc. The unknowledgeable programmer from the slides has no sufficient intuition in my opionion. You code C precisely because you want control over these things.

Personally I don't care about the tiniest details too much. I pick them up as I go and typically at least remember that there was something that I can look up again later. Also it's really easy to navigate around most pitfalls. As the first programmer says, "I would never write code like that".
