I tend to agree, but not quite fully. To me, it's not about low-level vs. high-level or distributed programming. Systems programming tend to fall into these categories:

- Running and managing a single system: kernels, drivers, programming tools (compilers, interpreters, assemblers, libraries, linkers, loaders, etc), admin tools, package managers, graphics servers, etc.

- Connecting multiple components/systems: protocol implementations (tcp/ip, rpc, etc), message brokers, servers/daemons (database, web, cache, etc), proxies, middleware, etc.

- Virtualization: emulation, sandboxing (docker, wasm), hypervisors, etc.
