I think there is an argument that Brainfuck [0], et al, is lower than C, given that it eschews variables and functions.

Low level means close to the processor, not small in scope.

You could argue brainfuck is machine language for a theroetical infinite tape machine, but such a machine can only exist when implemented in high-level software.
