POSIX Era is Gone
Published on 13 Dec 2022
TLDR, OS interface needs new layer of abstraction
TIL, the speed balance between I/O and compute is shifting in favor of I/O, which is partly why coprocessors and special-purpose accelerators are becoming more mainstream. Therefore, the POSIX era is over, and future designs need to transcend POSIX and re-think the abstractions and interfaces at a higher level. The operating system interface has to change to support these higher-level abstractions.
