Distributed systems require insanely hard math at the bottom (paxos, raft, gossip, vector clocks, ...) It's not how the human brain works natively -- we can learn abstract thinking, but it's very hard. Embedded systems sometimes require the parallelization of some hot spots, but those are more like the exception AIUI, and you have a lot more control over things; everything is more local and sequential. Even data race free multi-threaded programming in modern C and C++ is incredibly annoying; I dislike dealing with both an explicit mesh of peers, and with a leaky abstraction that lies that threads are "symmetric" (as in SMP) while in reality there's a complicated messaging network underneath. Embedded is simpler, and it seems to require less that practitioners become advanced mathematicians for day to day work.
