I have been working with embedded processors for about ten years, and was heavily involved in the core bare-bones software when we switched from 8051 to Cortex M0. Even on the 8051, only a few core functions for hardware interface was assembly code; less than a handful coders managed it. The rest was C. The M0 was similar: Very few of the developers of e.g. ANT or Bluetooth protocols ever touched assembly functions.

As we progressed to more advanced ARM variants, and even more so: More advanced on-chip peripherals, the tiny group of programmers handling assembly coded core functions stayed the same. The protocol and application group grew quite a lot, but none of them need to know the instruction set of the M33/M4s we are using nowadays.

We are currently in a transition from our proprietary bare-bones monitor, written almost entirely in C, to an open-source embedded OS written in C, with only very low-level, architecture dependent drivers in assembly. I would guess that 99+% of our system-on-chip code is C. And 99,99% of the application code for SoC is C, C++ or other HLLs.

We are still talking about SoCs with 64Ki RAM, 256Ki flash - but not 30 years obsolete 4Ki/16Ki units. Nor are we talking about the need for the CPU to regularly refresh dynamic RAM, relate to magnetic core memory or synchronize to mercury memory tubes.

Where do we draw the limit for what is relevant today? At mercury tubes? At 74 chips? Should 74 be forgotten, but CPD18xx taken as relevant influence on the choice of assembly vs. HLL code development?

There are two primary ways of getting old. Either you can turn into a grumpy old man, like Jeff Dunham's Walter, or you may lean back, saying, "Oh well, if that is the way the the next generation wants it, then let'em!" So let them have agile and github and google appstore and facebook and whathaveyou. For the part which is software development, it is HLL, whether you condone or condemn it.

My practical experience is that for embedded code, once you have got the (very limited) assembly functions required for hardware interfacing, C and other HLLs are most certainly suitable even for embedded programming.
