I loathe this line of reasoning. It's like saying "unless you wrote assembly, compiling your code could change what it does."

Guess what, the CPU reorders/ellides assembly, too! You can't trust anything!

Haha, what is this, the 90s?

Assembled instructions aren't even the lowest non-hardware stage in instruction execution. There's proprietary microcode sitting a level below your typical x86 ISA.

And even then, what if—God forbid—the hardware has errata. A line has to be drawn somewhere between trusting that what you write is logically correct at all stages below it. If someone is unable to trust that the environment they wrote code for works, they better start learning how to create PCBs and writing for FPGAs.

🙈🙉🙊

I know, but I didn’t want to scare the children.

I also chose to pretend it’s just little gnomes moving the bytes around. Less magic.

What are electrons, but a miserable pile of little magic gnomes? But enough talk... have a upvote!
