Don't underestimate the usefulness of hard real time io that's easy to implement. It's nice being able to be able to guarantee that some function will run exactly 0.2 microseconds after a voltage hits a pin, for example. Simple micro controllers where you program the bare metal will always have a place for this kind of thing. Doing that kind of thing in python on Linux is a can of worms. But, abstracting away comms between a python script on a pc to an arduino talking to sensors is definitely someone worth perusing, though one is basically there with pyserial and some glue code.
