Seemingly, no one uses assembly nowadays other than to develop device drivers, or the very core of OS kernels etc. Anyone has knowledge of it being currently used for other thin
The last time I came across assembler was when I used to hack the Quake I source code. All the math libraries (especially anything for dot products) were written in MASM by John Carmack. This stuff was floating-point intensive, and at the time C wasn't as good as expertly hand-crafted ASM for floating operations. Also, since computers were far more CPU-limited, and since Quake used the CPU for rendering, every single operation mattered, so ASM worked best.
