Sure, I never said it was irrelevant or a waste of time. It can be useful and interesting. It's just not necessary, and it doesn't tell you how computers really work.
I think we're just violently agreeing. You posted a few reasons people may feel compelled to use as reasons to learn C that are misleading. I'm just adding to that from my personal experience that learning C, even if you are not going to use it every day, also has a collateral advantage to help when talking to people who "think in C" as an abstraction.
Peace.
