What you say is true for all technology. We all use it, mostly with only a vague idea of how it works "on the inside". This is one of the advantages of componentization.
Where optimizing compilers are concerned, I have learnt to trust them as well. They are merely the latest in a "chain of trust" stretching from the CPU hardware through the microcode, etc. Just as very few of us build our own CPUs, very few of us manually optimize our own code.
As for Knuth, I must disagree somewhat. My copy of Knuth gets used a few times a year - not for the MIX code, but for the description and specification of algorithms. I find his language to be clearer than that of many authors who white books with titles like "Algorithms in <language of the month>", and usually with fewer errors.
On one level, I couldn't care less if my code were executed by tiny elves as long as they executed it correctly. On another, I share your shock at the lack of curiosity about the inner workings shown by so many young'uns.

I have never looked at assembly code, so I can't visualize it even in pseudo-code, but I have been developing an interest in learning the basic algorithms for byte manipulation just for fun and to perhaps optimize code better.
C? It was my first real love in programming languages because it satisfied my inner megalomaniac. With UNIX environment variables and C, I could rule the cyber world (muah-ha-ha-ha!). But that was ages ago - back when C++ was just a baby and not well loved. We were creating objects in C and saw no need for a new language to do that. So I image that if I bothered with C++, my answer would be yes, because I'd be learning C++ through the lens of C programming, which is how I expect to learn Rust (which is a just for fun thing I'm going to do).
I'm a php web developer, which is pretty much as far from C as one can get. It's a 'forgiving' language, which is to say, it won't let you (fill in the blank). It assumes what you want and does that, even if what you want is an endless fork loop (lol). There is no declaring of variables, no acquisition of memory, no requirement for garbage collection most of the time - you can even have variables that are one type in some cases and another type in other cases. It's very different from C. I have no experience with C# and wonder how like C it is. I would learn it just to see (no pun intended), but I think I'll learn Rust instead.
As to the unusual nature of this, I'm curious to find out, but I do think it rather rare. It is what I would look for if I were ever in the position of hiring.

Started with machine code. Went on to assembler, then C (with assembler functions, cos I could opimize better than the compiler). So I find it natural to think about what's happening at low-level.

I used to think that way about memory layouts in C/C++, but strings in the newer languages where everything wants to be on the heap make it kind of pointless.
I trust the optimizers in the compilers for the execution flow. (Unless it is a C compiler from DEC where I recommend /DEBUG to disable optimizations)

I will assume they are all hunt and peck when it comes to the keyboard!
If you can't laugh at yourself - ask me and I will do it for you.

(I may have posted this before, if so, apologies)
Back in the day when I used Wordstar to write all of our user manuals I had been really stuck into some heavy duty writing and had forgotten to save my work for some time ...
To close down Wordstar without saving any of your work required the rather complicated keystroke sequence of Ctrl+KQY.
Any other sequence would result in nothing happening or at worst an error message.
Any. Other. Sequence. Of. Keystrokes.
Enter my cat (kitten) ... took a stroll over the keyboard... Hesitated when I screamed, with its paw hovering over the Y. Looked me right in the eye and placed that paw down. Evil incarnate, I swear.

Back in the day when I was using Wordstar I was using it on Z80 Superbrains.
The reset for a Superbrain was to press the red keys at each end of the keyboard simultaneously. Something that YOU WOULD NEVER DO accidentally.
In comes my two year old daughter.
"Ooh look two red buttons", pressed simultaneously by index fingers of two hands.
BANG!!
All work gone!
Ah well. (I'm sure that those were the days!)

OMG - Superbrains ... me too! Those were days, not sure about the "the"
Did myself an injury trying to carry one of those into the warehouse - slipped on a step and landed sternum-first on the keyboard edge. The SB survived unscathed (well, we finally found the T key at the other end of the warehouse), but two of my ribs were broken!

Reminds me of a joke from many years ago about the TECO text editor[^] on DEC equipment. You could enter your full name and it would be a valid set of commands. It was interesting to see what actually happened.

Not really. He's more of a tester, but he does work his paws to the bone. It's a good thing the work isn't too ruff. He's shed all of his other dooties.

We have a couple of rescue GH's that come down to the beach, when they start to run the labs just stand there in awe, it is a wonderful sight to see them run just for fun!

I show him a few weeks ago a new-retro game on C64, and he got exited, first to play than to change (adding things that C64 cannot probably do  )
So we agreed I will teach him... So we started on how actually all that magic works on the lowest level (ones and zeros)...
After a few explanations he even more excited to learn...
