It's one of the last platforms that people still write a lot of hand written assembly for. Part of this is down to the assembler being very ergonomic and there being a very capable macro system available with macros provided for most system services. Part of it is due to the OS predating C becoming popular, so there are no headers files (just assembler macros) for many older system services (you can thunk them into C compatible calls, but it's sometimes more of a headache than just writing in assembler). Definitely C is becoming more popular lately on the platform, but you will still find a lot of people programming in assembler for a living in 2025. Its probably the only subfield of programming that uses handwritten assembly in that way outside of embedded systems.
