Nice points. I've prepared what I believe is a good non-exhaustive list without getting very specific. I could be wrong .. - Embarrassingly low-level (chip developers): OS, C/VHDL/Verilog, MA, DS, GPH, EE, Apathy, SE - The in-betweeners (kernel, device, storage developers): OS, C, MA, DS, GPH, Apathy, Crypto, SE - Low-Low-level systems: OS, C, DS, GPH, Apathy, Crypto, SE, FTDS, MSG, NW. - Low-High-level systems: C/Rust, DS, GPH, Apathy, HDS, Crypto, SE, FTDS, MSG, NW, TL. - Unicorn rock-star systems hacker (perhaps only a handful of these creatures exists :-): Multiple OS, C/Rust/JVM/Erlang/Haskell, Multiple MA, DS, GPH, EE, Crypto, FTDS, MSG, NW, HDS, SSE, TL. Abbreviations used: GPH = Good Programming Hygiene EE = Electronics and Electrical Engineering OS = Operating System MA = Modern Assembly DS = Data Structure FTDS = Fault-Tolerant Distributed System MSG = Messaging System NW = Networking TL = Toolings (the darlings of UNIX) HDS = High-Density Systems SE = Security Engineering
