Whilst not ever close to understand the details, I am still wonder on how memory and pointer manipulation especially in embedded system and system programming can be replaced other than by assembler. Of course once you have the core in c and assembler, you try to move to higher level or domain specific "language". Even word or this box in browser is high level supported ultimately in that.
