In the embedded world there is still enough of it. Today we had to free up 1200 bytes because our software did no longer run after adding 2 new features; not enough free memory. With higher level languages we would already have no chance with the previous features on the hardware, with asm we managed to optimize enough to free up the needed memory. It is amazing you always seem to be able to push it further. All that was a must in the 70-80s homecomputers as they were not (easily, without soldering generally) expandable, so you had to make it work on what was there. I got into my current work because I like that kind of optimizing and puzzling from when I did it in the 80s as a kid.
