A new, very interesting paper from Raman Sundrum - now at Maryland, where maybe he can bump into Ted Jacobson and Michael Levin more easily - entertains starting from a discrete viewpoint: "In this way, one may have a sequence of emergent phenomena: strongly-coupled discrete quantum system → continuum quantum field theory → Special Relativistic field theory → CFT → AdS General Relativity + gauge theory. ... Reading in reverse, one might well suspect that our own Universe has a discrete but strongly-interacting “DNA”."
