I talk to a lot of embedded people. Tiny machines are not going to
disappear anytime soon - they just go into smaller and smaller gadgets.
For example, there are still a noticeable segment of NOMMU CPUs, meaning
if you really target embedded, you need to learn how to live with vfork
You can't just handwave embedded away by assuming that "embedded will
get big enough for me to not really care about optimizing for size".
