Those that don’t need low level details can spend their professional career in languages like python and JavaScript while still have a sense of what lies beneath the abstraction.
For those that do want or need to go deeper, C is an excellent jumping off point into ASM and arch specifics.
Deliberate efforts to surface this deeper layer back to the programmer-facing ISA (VLIW, notably Itanium) failed spectacularly outside of niche applications. C and its contenders can't simply hop over the CPU abstraction presented to them without having to map backward from some lower-level model to the surface ISA it's forced to target then having the rug pulled every few years due to microarchitectural changes. It has managed to evolve surprisingly gracefully over decades from tiny 16 and 18-bit machines, sometimes segmented, to 32 and 64 bit machines, and even accommodating SIMD reasonably gracefully via intrinsics (which is about the best we can do at present, as CPUs continue to diverge wildly in this area, though I'm begrudgingly impressed by what modern compilers can do via autovectorization to optimize simple loops).
