Are lispers interested in permacomputing?
Given how easy it is to write a very basic R4RS interpreter or compiler it seems like the perfect language for a stack that an individual can fully understand from language implementation down to its assembler and machine code.
And that could be fully described/taught in like 2-3 books max.
Run on a vm that can, due to its aforementioned nature, easily be ported to any chips in existence which comes in as a major advantage once we start scavenging for random computer parts in the remains of our first apocalypse.
