That's why my (long after retirement) interest is mostly in MCU 
programming, currently the STM32F7 series.

The processors have all sorts of interesting memory management hardware 
built-in, including storage protection, but few people avail themselves 
of it.  For me, this allows this once-engineer to get back to playing 
with hardware without putting up with the nonsense of a massive 
operating system.  I find that very gratifying in my dotage.
